Poor Theodora Oglethorpe! Her biologist father has gone off to explore the jungles of Laos without her, her two best friends are away on vacation, and a long, hot, lonely Boston summer is all she has to look forward to.

Poor Gideon! Wycca, his pet wyvern, has disappeared through a magic hole in time in search of a place to lay her egg. Kobold, Gideon's rival wizard, wants nothing more than to capture Wycca and turn her against her master. In a desperate attempt to rescue Wycca from Kobold's evil clutches, Gideon follows her through the magic hole...and finds himself transported from his castle in thirteenth-century England to the terrifyingly modern world of Boston, Massachusetts, in the year 2002.

Little does Gideon know that what he needs most in order to find his wyvern is stuck to the bottom of Theodora's shoe. And little does Theodora know that Gideon is the reason why her summer vacation has begun to seem a whole lot more interesting...
