The secret of Lillian Velvet

Summary: Here are only a few of the wonderful, strange, and mysterious elements in this breathtaking visit to the Kingdoms and Empires: A very proper girl named Lillian Velvet, living a very lonely life with a nasty Grandmother. A jar of coins, each with the power to take Lillian on a journey to a different time and place...and also to grant a single wish. A small boy in a barn about to be crushed to death by a load of hay. A family, each member in mortal danger, who are strangers to Lillian (but whom clever readers will recognize). And a web of dangerous magic closing tight around all. Who IS this Lillian Velvet? And what is her secret?
