Lo Blacklock, a journalist who writes for a travel magazine, has just been given the assignment of a lifetime: a week on a luxury cruise with only a handful of cabins. The sky is clear, the waters calm, and the veneered, select guests jovial as the exclusive cruise ship, the Aurora, begins her voyage in the picturesque North Sea.

But when she finds herself trapped 300 miles north of the city, convalescing in a sleepy coastal town with her adult daughter Beth and teenage granddaughter Jack, Lana is stuck counting otters instead of square footage—and hoping that boredom won’t kill her before the cancer does.

Opal is a lot of things—orphan, high school dropout, full-time cynic and part-time cashier—but above all, she's a determined to find a better life for her younger brother Jasper. One that gets them out of Eden, Kentucky, a town remarkable for only two things: bad luck and E.

Her half-brother Ben didn’t sound thrilled when she asked if she could crash with him for a bit, but he didn’t say no, and surely everything will look better from Paris. Only when she shows up – to find a very nice apartment, could Ben really have afforded this? – he’s not there.

Melville Heights is one of the nicest neighborhoods in Bristol, England. It’s the sort of place where doctors and lawyers and old-money academics live. It’s not the sort of place where people get stabbed in the back 30 times with a kitchen knife in their own homes. Someone must have seen something. Newlywed Joey Mullen, for example, recently returned from four years of working in Ibiza. She and her husband, Alfie, are eager to find a place of their own in her hometown. But Joey finds herself distracted by the man next door, Tom Fitzwilliam.
