What Have We Done



In this “top-notch mystery thriller” (Publishers Weekly, starred review), What Have We Done is a tale about the lives we leave behind and the secrets we carry with us forever.

A stay-at-home mom with a past.
A has-been rock star with a habit.
A reality TV producer with a debt.
Three disparate lives.
One deadly secret.

Twenty five years ago, Jenna, Donnie, and Nico were the best of friends, having forged a bond through the abuse and neglect they endured as residents of Savior House, a group home for parentless teens. When the home was shut down―after the disappearance of several kids―the three were split up.

Though the trauma of their childhood has never left them, each went on to live accomplished―if troubled―lives. They haven’t seen one another since they were teens but now are reunited for a single haunting reason: someone is trying to kill them.

To survive, the group will have to revisit the nightmares of their childhoods and confront their shared past―a past that holds the secret to why someone wants them dead.

It’s a reunion none of them asked for . . . or wanted. But it may be the only way to save all their lives.

What Have We Done is both an edge-of-your seat thriller and a gut-wrenching coming-of-age story. And it cements Alex Finlay as one of the new leading voices in thrillers today.

“[A] top-notch mystery thriller . . . . Readers will eagerly follow the maze-like plot, with its many twists and turns, to the exciting conclusion. This isn’t to be missed.”—Publishers Weekly (starred review)

“Finlay has mastered the thriller genre with this novel . . . . Finlay superbly creates a character-driven coming-of-age tale that is full of twists."—Library Journal

“[Finlay’s novels] have earned him a reputation for producing suspenseful, fast-paced thrillers. As usual, his characters are well drawn, his writing is tight and vivid, and he keeps readers guessing with a series of twists and red herrings.”—Associated Press

“Finlay could fashion a white-knuckle cliffhanger out of a trip to the store, so plan to start and finish this on the same day, maybe the same afternoon.”—Amazon Book Review

“A thriller that will have your pulse and mind racing."—E! News 

“In the suspense/thriller genre, Finlay stands out for a couple of reasons. First, he uses multiple points of view to flesh out his plot and keep the pacing ultra-fast, while still being grounded and accessible. Second, he never shies away from a difficult scene, whether it’s an emotional arc that pushes his characters into totally new realms and opportunities for growth, or a particularly creative murder scene . . . . [What Have We Done] is a fast-paced and suspenseful thriller with just enough emotional grit to make readers care about the characters along with the mystery.—Bookreporter

“Explosive, whip-smart, and compulsively readable, What Have We Done sets a new high-water mark as Alex Finlay’s best thriller yet.”—Sarah Pekkanen, #1 New York Times bestselling co-author of The Golden Couple

“A next-level thriller that brims with dark surprises and unforgettable characters inextricably connected by their pasts, loyalties, and an unspeakable secret. Inventive, immersive, and downright addictive, What Have We Done had me flying through the pages. Put this one on the top of your to-be-read list.”—Heather Gudenkauf, New York Times bestselling author of The Overnight Guest

“Alex Finlay proves once again he’s a master storyteller. What Have We Done has unrelenting action, inspired characters, and an innovative, pulse pounding plot. Alex Finlay has become one of today’s top thriller writers. This is why. Read this book.”—Robert Dugoni, New York Times bestselling author

“This is the very best kind of thriller: fast, smart, and not a wasted word. Alex Finlay is a master at making the pages fly past.”—James Kestrel, Edgar-award winning author of Five Decembers

“[Finlay] skillfully blends storylines past and present in What Have We Done, resulting in a suspense-filled romp.”—Bookpage

“Alex Finlay’s What Have We Done is the type of thriller that should come with a seatbelt and safety goggles. Finlay wastes not one page before throwing readers into a tailspin, sending his plot off in a direction readers could hardly expect. By that point—again, just a few page turns into this novel—readers are hooked and there is no stopping until the cover is closed for good.”—BoloBooks

Finlay is back in stunning fashion with the darkly brilliant What Have We Done. . . This is a flat-out fantastic psychological noir tale with hereos plagued by an angst-ridden past they can't escape.”—Jon Land's The Thrill List, BookTrib

Finlay constructs an edgy storyline and creates characters whose troubled lives and flawed natures simultaneously engage the reader’s sympathy and distaste as they fight for their lives — and not solely with nonviolent means.”—Richmond Times-Dispatch
