When librarian Kathleen Paulson moved to Mayville Heights, Minnesota, she had no idea that two strays would nuzzle their way into her life. Owen is a tabby with a catnip addiction and Hercules is a stocky tuxedo cat who shares Kathleen's fondness for Barry Manilow. But beyond all the fur and purrs, there's something more to these felines.

When murder interrupts Mayville's Music Festival, Kathleen finds herself the prime suspect. More stunning is her realization that Owen and Hercules are magical-and she's relying on their skills to solve a purr-fect murder.
