At 151 pages, _Killing with the Edge of the Moon_ is an evening's read, but what an enchanted evening it is!
I think Attanasio intended _Killing_ as a young adult novel, though I'm not absolutely certain of that. If you're a parent, though, there's nothing in here that's inappropriate for your teen. Despite the cover copy's mention of the "erotic Otherworld," all sexual content is of the briefly-implied sort. Attanasio's Otherworld is seductive, but he does it without filling the tale with smut.
The plot draws upon several old myths: Orpheus and Eurydice, Tam Lin, the Wooing of Etain, and a dash of the Mabinogion. I'm always up for a good "rescuing a loved one from the Otherworld" story. _Killing_ has a deeply archetypal feel due to its basis in the myths, and at the same time, the story is made fresh and individual by the delightful protagonists. Chet is my favorite; I love his leap of faith into a world he doesn't quite believe in, his sense of duty, and little details like the bad poetry he writes for Flannery and his musings about the proper swearwords to use when lost in Elfland. Flannery is also great, a defiant girl who cares more for animals than people; and Nedra, Flannery's Wiccan grandmother, who is more than she seems.
Attanasio is a strongly visual writer. He bills _Killing with the Edge of the Moon_ as "A Graphic Novel (without illustrations)." The prose sets the scene well, whether he's describing an idyllic meadow or a hellish volcanic cavern. Attanasio uses simpler prose for scenes that take place in our world and lush prose for Otherworldly scenes, and it works well. Like the ritual gown that Nedra makes for Flannery, the prose is studded with bits of shining beauty.
_Killing with the Edge of the Moon_ feels more like a fairy tale than a traditional novel, and will be enjoyed by anyone who likes stories of teens confronting the Otherworld.
