Get the Earth's Last Gambit bundle, featuring all four books in this first-contact series blending hard sci-fi and edge-of-your-seat action.

When an experiment to study quantum uncertainty goes spectacularly wrong, physics student Bill Rustad and his friends find that they have accidentally created an inter-dimensional portal. They connect to Outland - an alternate Earth with identical geology, but where humans never evolved. The group races to establish control of the portal before the government, the military, or evildoers can take it away. Then everything changes when the Yellowstone supervolcano erupts in an explosion large enough to destroy civilization and kill half the planet.

NASA finally made it. The very first human has just set foot on the surface of our neighbor planet. This is the start of a long research expedition that sent four scientists into space. But the four astronauts of the NASA crew are not the only ones with this destination. The privately financed "Mars for Everyone" initiative has also targeted the Red Planet. Twenty men and women have been selected to live there and establish the first extraterrestrial settlement.

Get ready to experience two more origin stories in the Backyard Starship universe.

The Galahad, a faster-than-light spacecraft, carries 50 scientists and engineers on a mission to prepare Kepler 452b, Earth's nearest habitable neighbor at 1400 light years away. With Earth no longer habitable and the Mars colony slowly failing, they are humanity's best hope. After 10 years in a failed cryogenic bed - body asleep, mind awake - William Chanokh's torture comes to an end as the fog clears, the hatch opens, and his friend and fellow hacker, Tom, greets him...by stabbing a screwdriver into his heart. This is the first time William dies.

Worse, she claims to have permission from the Wardens to unleash them upon the system.

Dr. Tyson Klein is a quantum physicist who has dedicated his entire life to his research. At CERN, he analyses data generated by the Large Hadron Collider, the world's biggest and most powerful particle accelerator. Now, Ty believes he's found a pattern in its output. It looks like an organised data stream, being broadcast over what he calls a quantum radio. Could it be a signal from another universe? A message sent from the future? Or something else entirely?

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?
