Bee thinks she has everything: a successful business repurposing wedding dresses, and friends who love and support her. She’s given up on finding love, but that’s fine. There’s always Tinder. Nick thinks he has nothing: his writing career has stalled after early promise and his marriage is on the rocks, but that’s fine. There’s always gin. So when one of Nick’s emails accidentally pings into Bee's inbox, they decide to keep the conversation going. After all, they never have to meet. But the more they get to know each other, the more they realize they want to. When their efforts to meet in real life fail spectacularly, Bee and Nick discover that they’re actually living in near-identical but parallel worlds.

Reclusive bookseller Shaun Ryan has always believed that his uncle Teddy died in a car accident 20 years ago. Then he learns the truth: Teddy fled his home in Catholic, deeply conservative County Wicklow, Ireland, for New York and hasn't been heard from since. Shaun’s search for his uncle is unsuccessful until he's contacted by Chris Guzman, a woman who runs a website dedicated to matching missing-persons cases with unidentified bodies. Chris and her team of cold-case obsessives suspect that Shaun is looking for the "Boy in the Dress," one victim in a series of gay men murdered by the same killer. But who are these internet fanatics really, and how do they know so much about a case that has stumped police for decades?

Desperate to attract subscribers to his fledgling website, ex-adrenalin junkie and slacker Simon Newman hires someone to guide him through the notorious Cwm Pot caves, so that he can film the journey and put it on the internet. After a brutal struggle for survival, Simon barely escapes with his life, but the gruesome footage he managed to collect down in the earth's bowels goes viral. Ignoring the warning signs of mental trauma, and eager to capitalize on his new internet fame, Simon latches onto another escapade --- a trip to Everest. But up above 8000 feet, in the infamous Death Zone, he'll need more than his dubious morals and wits to guide him, especially when he uncovers the truth behind a decade-old tragedy --- a truth that means he might not be coming back alive.
