The Mark of Merlin
"Carla Murdoch had learned what it was to be alone, growing up on different army posts. But now her loneliness is terrible--for her officer father met a mysterious death on a foreign battlefield, and Carla has been sent to live in her new guardian's New England mansion-- a remote, snowbound place where she finds she isn't really wanted. Together with her dog, Merlin, Carla must make a new start and face demons within and without--for her father's killer is now on her trail, too!"--Amazon.
