From the author of The Aftermath comes the story of a whirlwind friendship--and the dark secrets lurking beneath it.

After a tumultuous marriage, Mary Wilson is happy in her uncomplicated life, focusing on her twelve-year-old son. She's always been content with her little family--but then she finds an old postcard that throws her whole past into question...

When an invitation arrives for her high school reunion, Mary jumps at the chance of a distraction from the shock discovery, and meeting her old classmate April feels like a gift. Despite barely remembering April, Mary throws herself into the new friendship and finds her previously quiet social life reinvigorated.

But as the bonds between them are forged, Mary finds herself drawn further and further into April's life and marriage, increasingly fearing that everything is not as perfect as it seems. Is her own painful past clouding her judgement, or is Mary right to suspect that the people she trusts most are the ones with the most to hide?
