Everyone knows there's something slightly "off" about Josephine Watts.

The summer before fourth grade, she befriends Colten, the new neighbor boy.

He's into piano and baseball. She has a penchant for dead things.

Their unlikely friendship lasts until graduation when Colten breaks her heart.

Seventeen years later, the boy she once hated is back in her life-a single dad and a homicide detective looking over Josephine's shoulder while she performs autopsies as one of Chicago's most gifted forensic pathologists.

When fate throws them a curveball, and Colten saves her life, Josie's left with images that keep her awake at night, images she can't explain.

Colten's determined to marry the girl he's always loved, but Josie's not planning a wedding. She's too consumed with unspeakable events that happened over a century ago.

He wants to believe her, but he can't understand her.

If he can't understand her, he can't stop her from going too far.

If he can't stop her, he can't save them.

And without Josephine Watts ... well, he can't imagine that world.
