There are doors that leak magic into the mortal realm in places one would think insignificant. Seventeen year old Nathalia was fortunate - or perhaps unfortunate - enough to discover such a place.
Nathalia has no memory of returning home after accidentally falling into Gelid lake, rumored to have lethally cold water.Nathalia tries to come to terms with the new reality when the lake's snarky guardian, an immortal shape-shifter named Cole, is summoned to guide her on a life-altering adventure that will either make or break her.
An unlikely friendship forms between them, finally offering her the affection she's never had - but when Cole's dark secrets reveal themselves, uncertainty settles in Nathalia's mind. Can she leave her morals behind to share Cole's immortal burden, or will she be left to live alone for her eternal existence?
