From the bestselling coauthor of Hank Zipzer, fast-paced adventure meets art history in the final book of this thrilling series

The adventure reaches its climax as Tiger and Luna enter a famous painting by Diego Rivera. Only this time, they're not alone. The kids are accompanied by Viola, the owner of the fantastic frame and mother of the boy who went missing inside it over fifty years ago. As the trio traverses the world of The Flower Vendor (Girl with Lilies), can they end Viola's search once and for all?
