Actually it's 2 books - Book 1 is Knight of Ghosts and Shadows, while Book 2 is Summoned to Tourney. This is Ms. Lackey using elves again but in an urban setting (and with plenty of music around naturally). Although I liked Knight well enough, I looked at it as more of a set up for the 2nd book. Of course, Summoned is set in San Francisco (which I visited in April 2005), so it held more of my interest. :-)
But I liked both books well enough that I'm considering buying the paperback at some point and keeping it my book collection.
Really enjoyed this as I do all the Bardic Elves storys. This has a neer do well human freeing an elve. Some trips to their world, Underhill and plenty of magic. Mixing L.A. and Underhill makes for some interesting scenes. Not a great book but fits in with the others like it. Good reading.
Fun idea -- that an itinerant street musician's songs awaken an enchanted elven prince in contemporary Los Angeles -- that gets tangle up in elven and human and wiccan magicks. I liked the notion that certain songs (particularly the Celtic ones) can unlock magic, but had a bit of difficulty with elven horses that could diguise themselves as motorcycles.....
