For fans of How to Train Your Dragon comes the final adventure in the Dragon’s Guide series by two-time Newbery Honor winner Laurence Yep and Joanna Ryder, featuring enchanting artwork by Caldecott Honor winner and Harry Potter illustrator Mary GrandPré.
 
Plucky pair Winnie and Miss Drake are traveling back in time to the 1915 San Francisco World’s Fair. Waiting in the past are Winnie’s great-grandfather Caleb, Laura Ingalls Wilder, and a centuries-old mystery: Who stole the Heart of Kubera necklace? Despite the excitement, Winnie’s only wish is to lose Rowan, an unusual boy who has the annoying habit of showing up at inconvenient times. But the wise Miss Drake knows her pet Winnie should be careful what she wishes for—especially when her wish-granting souvenirs follow them home.

“Yep and Ryder keep the magic coming with their whimsical fantasy, enhanced by GrandPré’s sweet drawings. The story positively vibrates with fun.” —Kirkus Reviews
 
“Warm humor, magical mishaps, and the main characters’ budding mutual respect and affection combine to give this opener for a planned series a special shine that will draw readers and leave them impatient for sequels.” —Booklist, Starred
