War for the Oaks by Emma Bull

Guitarist and singer Eddi McCandry has just left a floundering band and her boyfriend when a Phouka, a man who at times is a talking dog, becomes her guardian at the behest of the Faerie Folk. Eddi soon finds herself involved with warring Faerie groups, the Seelie Court and its noble queen versus the Unseelie Court, ruled by the evil Queen of Air and Darkness. The Seelie Court has chosen Eddi because there's "power in a mortal soul that all of Faerie cannot muster." The Faerie need a mortal to give them the mortality on the warring field as it is the only way to have casualties.

In between the battles and conflicts Eddi assembles a new band composed of her close friend Carla on drums, Dan Rochelle on keyboards, mumbling Hedge on bass and Willy Silver on lead guitar. Together they become part of the magic and form the base for Eddi's own powers, which she has acquired from her new place in Faerie. She decides to name the new band "Eddi and the Feys" as a kind of inside joke to her new life. But it will take all the band's power, all that the Seelie court has to offer, and a bit of pure luck besides to win the battle for Minneapolis. Especially when nothing is quite what it seems, for if the Fay never lie, they still can twist the truth to the quick.

The real strength of the story is pure knowledge of rock music and the field, the contribute to the climax, a struggle between Eddi and the dark queen at a concert.

I read this book several years ago and was really pleased to get to read it again for my bookclub. What fun, as it is still as fresh and innovative as the first time I read it. It reminds me why I enjoy urban fantasy and need to read more again.
