Showing After You by Julie Buxbaum

Ellie's life is turned upside down when she learns the heartbreaking news that her best friend, Lucy, has been murdered.And, as best friends do, Ellie drops everything to travel to London to pick up the pieces.

Desperate to help Lucy's traumatized child, who has simply stopped speaking, Ellie turns to the book that gave her comfort as a child - The Secret Garden. And while its story of hurt, magic and healing blooms around them, so too, do the secrets Lucy kept hidden, even from her best friend.

As Ellie peels back the layers of her friend's life, she's forced to confront her own as well. Suddenly her carefully constructed existence spins out of control in a chain of events that will transform her life - and the lives of those around her - for ever.
