There's a fine line between the living and the dead, and Marshall is determined to cross it in this gut-wrenching debut novel.
Ever since the car accident that killed his identical twin brother, Marshall Windsor has been consumed with guilt and crippled by the secrets of that fateful night. He has only one chance to make amends and set things right. He must find a thin space—a mythical point where the barrier between this world and the next is thin enough for a person to step through to the other side.

But when a new girl moves into the neighborhood, into the exact same house Marsh is sure holds a thin space, she may be the key—or the unraveling of all his secrets.

As they get closer to finding a thin space—and closer to each other—March must decide once and for all how far he's willing to go to right the wrongs of the living...and the dead.
