"I loved it." --Sally Hepworth, New York Times bestselling author.

In this haunting tale about the bonds between sisters, one young woman must follow the invisible thread that connects her to her missing twin before someone else can sever it for good.

Twin sisters May and June couldn't be more different. May is quiet, self-conscious, withdrawn; June is boisterous, beautiful, magnetic...and missing.

It's been a year since June disappeared, a year of May waiting for her to turn up with an explanation of where she's been and why she left. But with the discovery of an old newspaper article comes a secret: their mother once vanished, too, on the same date when she was nineteen years old.

Just like June.

This was no coincidence. June was investigating this buried family mystery, and she left May a series of clues to pick up where she left off. Now, if May wants to find June, she'll have to retrace her footsteps through their mother's past.

The more answers she digs up, the more questions May has. And the biggest one of all: When her sister's trail of breadcrumbs runs out, what or who will she find?
