Perfect for you if...

  • You enjoy thrillers that weave past and present together, where the mystery unfolds through flashbacks that slowly recontextualise everything.
  • You're drawn to character-driven stories where the emotional weight matters as much as the plot mechanics.
  • You like books that tackle trauma and institutional abuse without flinching, where the stakes feel deeply personal.

Maybe not for you if...

  • You prefer contained, puzzle-box mysteries where the reader can solve the crime alongside the detective.
  • You want light, quick reads without heavy thematic material about childhood suffering.
  • You need redemptive or hopeful endings. This book sits in grey moral territory.

About this book

What Have We Done follows three people whose lives intersect around a deadly secret. Twenty-five years ago, Jenna, Donnie, and Nico were close friends at Savior House, a group home for teens without parents. They experienced abuse and neglect there. When the home closed following the disappearance of several residents, the three were separated. Each went on to build a life—a stay-at-home mom, a former rock star, and a reality TV producer—but they carry the trauma of their childhood with them. They have not seen each other since adolescence until circumstances force a reunion: someone is attempting to kill them. To stay alive, the three must confront the painful memories of their time at Savior House and uncover the secret from their shared past that explains why they are being targeted. The novel weaves together a thriller plot with the emotional weight of their coming-of-age experiences.
