From the Publisher:
Who killed the cat?
Anna Lee finds herself catapulted into the flamboyant rock world of Shona Una. Protecting a rock star on tour is hard enough at the best of times, but a hard job is made impossible when Anna has more trouble from the singer's bizarre entourage than from mysterious threats and her new-found knowledge of Shona's past. How can Anna help a client who has treated her as an enemy until it is far too late?
