Rachael has traveled to Whitehaven to visit her father, a trek she can not help but dread given his recent descent into madness. Upon her arrival she realizes his deterioration has not only been mental, it's been physical as well. His death comes as no surprise, but what she discovers soon after, is shocking when his burden becomes hers. Lock is a banished spirit who must attach himself to a human host in order to hide from those who would drag him back to hell to be destroyed. When he meets Rachael he finds more than a host, he finds an ally. Together they must defeat each of the seven sins in order to guarantee Lock's safe passage into the Third Realm, a loophole in creation that would allow him to escape hell and have peace at long last. Through their unlikely friendship, other banished spirits flock to them in hopes of a peace they hadn't dreamt possible.
