About this listen
When the strange fossil she'd discovered ended up giving her a trip to Mars, Helen Sutter thought she'd gone about as far as any paleontologist would ever go in her lifetime. But when you've also married A.J. Baker, overconfident super-sensor expert for the only private agency in space (the Ares Corporation), and your best friend Madeline Fathom Buckley is a former secret agent who's just signed on as the chief of security for the newly created and already embattled Interplanetary Research Institute of the United Nations, there's always somewhere farther to go.
The newest discoveries will take her, A.J., and their friends Jackie, Joe, and Madeline to the mysterious asteroid Ceres and beyond, in a desperate race to Jupiter's perilous miniature system of radiation-bombarded moons. The next gold rush is on - for alien technology, hidden in lost bases around the system. And there are people willing to do anything to get it - even plan the first interplanetary war, 400 million miles from home!

A daring and resourceful paleontologist uncovers something at the infamous K-T boundary marking the end of dinosaurs in the fossil record - something big, dangerous, and absolutely, categorically impossible. It's a find that will catapult her to the Martian moon Phobos, then down to the crater-pocked desert of the Red Planet itself. For this mild-mannered fossil hunter may just have become Earth's first practicing xenobiologist!

Story
There he was in his sailboat in the middle of the Atlantic, all alone and loving it. Well, there was a US Navy carrier group on his southern horizon, but he was a Navy guy himself, so he didn't mind. Then came the UFOs, hurtling in from the Outer Black to overfly the carriers at Mach 17. Their impossible aerobatics were bad enough—but then they started shooting at each other, and at the Navy, with nukes. Little ones at first, but winding up with a 500 megatonner at 90 miles that fried every piece of electronics within line-of-sight.

Story
In this alternate history of the American frontier and the Jacksonian era, a small change takes place in the Battle of the Horseshoe Bend during the War of 1812. What results is a cascade of new developments that becomes an avalanche. In our world, Ensign Sam Houston, just turned 21, led the charge on the creek barricade in that battle and almost died from a terrible wound that took him a year to recover from. In this world, his wound is minor, so he is able to continue fighting the British—and develop his close relationship with Andrew Jackson much sooner.

It was supposed to be a simple test flight, one that pilot Ariane Austin was on only as a last-ditch backup; intelligent, superhumanly fast automation would handle the test activation and flight of humanity's first faster-than-light vessel. But when the Sandrisson Drive activated, every automated system crashed, the nuclear reactor itself shut down, and only the reflexes and training of a racing pilot saved the test vessel Holy Grail from crashing into the impossible wall that had appeared before them.

Few know the warship’s actual name. But everyone has heard the rumors. The PUV James Keeling can do something no other vessel in existence can do—slip into another dimension, travel undetected, then re-emerge onto our plane and surprise enemy targets. But the thing that makes the Crypt unique also makes it a nightmare for those onboard; interdimensional travel causes hallucinations, violent behavior, and psychotic breakdowns. Keeling could be the Union’s greatest weapon, a game-changing asset that can defeat the bloodthirsty zealots of the Purist Nation, the Union’s mortal enemy.

Stephanie Harrington had always expected to be a forest ranger on her homeworld of Meyerdahl until her parents relocated to the frontier planet of Sphinx in the far distant Star Kingdom of Manticore. It should have been the perfect new home - a virgin wilderness full of new species of every sort, just waiting to be discovered. But Sphinx is a far more dangerous place than ultra-civilized Meyerdahl, and Stephanie's explorations come to a sudden halt when her parents lay down the law: no trips into the bush without adult supervision!

Story
In the 25th century, humans have conquered space. The advent of faster-than-light travel has opened up hundreds of habitable planets for colonization, and humans have exploited the virtually limitless space and resources for hundreds of years with impunity. So complacent have they become with the overabundance that armed conflict is a thing of the past, and their machines of war are obsolete and decrepit. What would happen if they were suddenly threatened by a terrifying new enemy?

Story
Seventy years ago, the interstellar supercarrier Ark Royal was the pride of the Royal Navy. But now, her weapons are outdated and her solid-state armour nothing more than a burden on her colossal hull. She floats in permanent orbit near Earth, a dumping ground for the officers and crew the Royal Navy wishes to keep out of the public eye. But when a deadly alien threat appears, the modern starships built by humanity are no match for the powerful alien weapons.

Story
They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

Story
They tried to destroy our planets. Our way of life. They tried to send us into extinction. But we, the Coalition, fought them and won. That was a decade ago. They’re known as the Host: a cabal of aliens seeking to dominate our sector of space. And they’re back - with help from a powerful new enemy. We’re outnumbered and unprepared. But there is hope. An ancient race of long-dead but technologically advanced aliens called the Navigators have a ship called the Blackstar that could potentially turn the tide. That is if I, Kai Locke, a humble ship racer, can find it and learn how to harness its power in time.

The year is 2650. Seventy-five years ago, an alien fleet attacked Earth. Without warning. Without mercy. We were not prepared. Hundreds of millions perished. Dozens of cities burned. We nearly lost everything. Then the aliens abruptly left. We rebuilt. We armed ourselves. We swore: never again. But the aliens never came back. Until now. With overwhelming force the aliens have returned, striking deep into our territory, sending Earth into a panic.

Our Heroic team continues there adventures!
On rare occasions I have read stories with the premise that someone or something with intelligence was on Earth in the Age of Dinosaurs. Boundary takes this to the Nth degree when a paleontologist excavates a skeleton like none other ever found on earth, surrounded by a pack of dead predatory raptors like you may have seen in the movie Jurassic Park. The dinosaurs all exhibit strange bone damage of uncertain provenance. This starts the greatest adventure in human history in motion, from 65 million year old remains to other evidence of ancient aliens.
From there the story grows far beyond expectations as our intrepid crew explores the remains the ancient aliens left behind on Phobos, Mars and now onward to Ceres!

Enjoying this series so far narration is very good
Little heavy on the romance. but this is a Eric Flint influence. The story does have good pacing and the characters are believable.

Really Disappointing Narration
Really liked the story, but the narrator nearly killed it for me. He consistently pauses in the most unnatural places. difficult listen due to narration.

Almost five stars
I basically listened to the first and second books in this series in a single huge gulp. And the third book is downloading to my computer as I write this review. So do I recommend this series? Yes. Heck, yes.
Now for the whining: The characterizations are great. I suspect this is Eric Flint's contribution. Most of his books do a good job with characters. And I love the fact that there is actually science in this book. A lot of science fiction is close to completely science-free. But there is something missing. A sense of wonder over the amazing discoveries they are making. It's like a child in a toy store. "Oh, look at this toy. Oh, there's something else. Here's something else..." They don't linger to savor discoveries. It's like the story is approaching a climax and then backs off just short of it time after time.
So I feel a bit unfulfilled after listening to the first two books, but only a little. I really enjoyed the ride. And I'm really looking forward to the third one.

not amazing but still decent
story is very technical, so if dry science bores you, this might not be the book for you. narrator is bad. Mispronunciations and horrible cliché accents abound. if you have time, read it instead
