Showing Kitty and the Midnight Hour by Carrie Vaughn

Kitty Norville is a midnight-shift DJ for a Denver radio station - and she also happens to be a werewolf. One night, sick of the usual lame song requests, she accidentally starts 'The Midnight Hour', a late-night advice show for the supernaturally disadvantaged. Almost immediately she's deluged by calls from desperate vampires, werewolves and witches from all across the country, wanting to share their woes and ask her advice. Kitty's new show is a raging success, but it's Kitty herself who could use some help, not least because her monthly change is a deep and dark secret to all but a very special few. And when she finds one very sexy werewolf-hunter on her tail, not to mention a few homicidal undead, she realises she may just may have bitten off more than she can chew . . .
