Seven months ago, the sea took Wren Calloway's mother. Or so everyone in Halloway Harbor believes - until a water-stained box washes up on the rocks below the lighthouse, and Wren's careful, grief-numbed life cracks wide open.
Inside is an atlas unlike any other. Its coastlines shift from one page to the next, marking places that don't exist on any real map - and it seems, impossibly, to be finding things that are lost. A missing shoe. A sunken photograph. A truth her father and her once-estranged aunt have both been guarding for twenty years.
As autumn closes in on the small Maine fishing town, Wren follows the atlas's strange guidance - with help from Theo Marsh, the boy next door who's loved her quietly since they were twelve, and Priya, her fiercely loyal best friend - through a parade-night confession, a cliffside accident that nearly costs her everything, and a family secret that reaches back two decades to a boy who drowned before she was born.
The atlas is counting down to something. A date. A tide. A last chance.
Wren has days to decide how far she's willing to go to bring her mother home - and what it will cost the people she loves most to find out the truth.
The Map of Almost Gone is a moving, atmospheric story about grief, hope, and the terrifying, necessary work of believing in something impossible when everyone else has stopped believing at all. Perfect for fans of We Were Liars, Nina LaCour, and anyone who has ever needed to believe that some things that are lost are only waiting to be found.
