Evanescent

One human life each year. That's the deal made between Earth and the fae realm of Ilia, to keep the peace. Katie Montgomery was supposed to be a tribute, but when she's spared as a baby, she's sent across the country for her safety. Years later, after a series of disturbing events in her hometown in Oregon, she returns to her birth town in Maine, opening an apothecary and quickly gaining favor with the locals. But what she doesn't know is that Ilia is still owed a life - particularly hers - and some would go to extraordinary lengths to see it happen, and one would do anything to save her.
