A to Z Mysteries Super Edition #10: Colossal Fossil

In the tenth A to Z Mysteries Super Edition, Dink, Josh, and Ruth Rose have a sleepover . . . with a Spinosaurus!

It's sleepover night at a science museum in Boston. Dink, Josh, and Ruth Rose can't wait to settle their sleeping bags near the museum's colossal fossil--a giant Spinosaurus skeleton--and tour the exhibits long after closing time. But after they fall asleep, they wake to a terrible crash! Is the dinosaur fossil damaged? Or is there another big problem at the science museum?

Help Dink, Josh, and Ruth Rose solve mysteries from A to Z! From The Absent Author to The Zombie Zone, there's a mystery for every letter of the alphabet, plus ten super editions with even more A to Z fun. And don't miss Ron Roy's series for younger readers, Calendar Mysteries!
