The Mirror of Eternity — Garrett Boatman

In the Desert of Dudael, the demon Azazel is freed from the pit where he has dwelled for millennia. On the frozen world of Abyss, fallen angels banished from earth in the time of Enoch, prepare for their return. But the world is vanishing. Soon there will be battleground for neither man nor demon. Rick Scott has sworn off magic, but when he receives a summons from his former mentor, he must travel the ravaged wasteland of time and gaze into the mirror of eternity before the world plunges into the white-hot singularity of creation. But there are creatures that dwell within time's labyrinth who would sate their unspeakable hunger on the unwary traveler.
