Cats know about ghosts. But what if there's a whole army of them? Sassycat has moved into a new neighbourhood and the local animals are acting very weirdly - they're so grim and defensive. No welcome here for a fun-loving cat! And why is the cemetery off limits? Sassycat's humans aren't much help either. Even her best friend Rebecca is distracted and troubled by nightmares. It's lucky that Sassycat is such a sassy cat. But then, it's hard not be confident when you've got four white socks, a perfect tail and whiskers to die for. She'll solve the mystery, even if she has to do it all by herself.
