Perfect for you if...

You love emotional family mysteries where the real secrets are messier than the setup suggests.
You appreciate when a book splits its time between past trauma and present-day reckoning with equal weight.
You're drawn to stories about sisters where the relationship itself is the central tension, not just the plot device.

Maybe not for you if...

You need a fast-paced page-turner with twists that land every chapter; this unfolds more like real grief than a thriller.
You prefer standalone mysteries where everything wraps up neat; this sits with painful ambiguity.
You want a straightforward reunion story; this is really about why some separations might be necessary.

About this book

Kit, an ER doctor in Santa Cruz, believes her sister Josie died fifteen years ago in a terrorist attack on a train. When Kit sees a woman who bears an unmistakable resemblance to Josie in live news coverage of a club fire in Auckland, her world is upended. The discovery prompts Kit to travel to New Zealand to search for the sister she thought was gone. As Kit begins her journey, she recalls memories of her past with Josie: days spent on the beach together, a lost teenage boy who became part of their family, and a trauma that has haunted them both throughout their lives. To reunite with her sister, Kit must unearth long-buried secrets and confront a devastating truth that has kept them apart. Reconciliation may require them to lose everything.
