Guardian Glass https://www.amazon.com/gp/product/B008GBVGDA/ref=dbs_a_def_rwt_hsch_vapi_taft_p10_i0
Fourteen years ago, the gateway to Faerie opened and the denizens spilled forth into our world, fleeing a war that was destroying their world. The Faerie, Elves, Imps, Goblins, Vampires, Werewolves, Dragons and thousands of other supernatural creatures infested our world, struggling to co-exist with humanity. And they brought back the magic. It’s not a sane world any longer.
When a child is kidnapped through magic, Guardian Glass is ordered to find her, by any means necessary. As he begins his investigation, it becomes increasingly clear that nothing is what it seems…and that the kidnapping is only the first step in a plot that strikes at the very heart of magic, and threatens to plunge humanity into eternal darkness.
