The highland falcon thief by MG Leonard and Sam Sedgman

A mystery on a steam train?  Well, what's not to love?!  Really enjoyed this one, which has everything from stowaways, dogs, missing jewels, royalty and the excitement of a steam train journey.  I enjoyed all the little details about the train journey, and the train itself, as well as enjoying the mystery.  Hal is a great character, and I raced through the book.  The mother in me felt sick at some of the super dangerous antics that ensue on the train, but put your grown-up head away and just enjoy the ride :)
