The Harbinger Tome 1
Storm and Fury

Eighteen-year-old Trinity Marrow may be going blind, but she can see and communicate with ghosts and spirits. Her gift is part of a secret so dangerous that she's been in hiding for years in an isolated compound guarded by Wardens - gargoyle shape-shifters who protect humankind from demons. If the demons discover the truth about Trinity, they'll devour her to enhance their powers. When Wardens from another clan arrive with disturbing reports that something is killing both demons and Wardens, Trinity's world implodes.
Not least because one of the outsiders is the most annoying and fascinating person she's ever met. Zayne has secrets of his own that will upend her world yet again - but working together becomes imperative once demons breach the compound and Trinity's secret comes to light. To save her family, and maybe the world, she'll have to trust Zayne. But all bets are off as a supernatural war is unleashed...
