Greysteel's Ghost (Paperback) (ISBN-13: 9780006393993)

It happens so quickly: a car shoots out from the curb, hits Fiona's father and then speeds away. Is it an accident? Or is it a warning to Gavin and his Scottish cousin, Fiona, to turn back? Gavin is in Scotland to hike across the moors, and Fiona's dad isn't about to let a broken leg stop the kids' fun. Fiona and Gavin will have to go on without him.

A broken leg turns out to be the least of their troubles as the cousins unwittingly stumble onto a monstrous murder plot to kidnap a girl--and get caught by the conspirators. Managing to escape, Gavin and Fiona find themselves in the middle of a mysterious scheme and a race against time across the Scottish moors. Greysteel's Ghost is a terrific, straight-up adventure story from an author who knows exactly what his middle-grade fans want--a page-turning mystery driven at a souped-up pace.
