For with the Magic came the Bad Thing, and the Faerie, and then the cool. . .and the resurrection of a primordial war with a forgotten people-a war that not only the Hastings but the whole human race could lose. From the Paperback edition.
This was a good dark fantasy set in the modern day. I liked the intermixing of Celtic mythical creatures with twentieth century people. I especially liked how the twins Patrick and Sean learn how to cope in the faerie world.
