Roommates Skunk and Badger head out on a rock-finding expedition that becomes much more dangerous than they ever expected in this second book of the national bestselling and award-winning odd-couple series that has been compared to Wallace and Gromit and Winnie the Pooh

Buried in the heart of every animal is a secret treasure. Badger’s is the Spider Eye Agate, stolen years ago by his crafty and treasure-trade-dealing cousin, Fisher. Skunk’s is Sundays with the New Yak Times Book Review.

When Mr. G. Hedgehog threatens to take the Book Review as soon as it thumps on the doorstep, Skunk decides an adventure (“X marks the spot!”) will solve both their problems. Badger agrees, and together they set off for his favorite campsite on Endless Lake. But all is not as it seems at Campsite #5. Harrumphs in the night. Unexpected friends.

Then Fisher appears, and Badger knows something is up.

Something involving secrets, betrayals and lies.

And a luminous, late-Jurassic prize.

In a volume that includes full-colour plates and additional black-and-white illustrations by Caldecott medallist Jon Klassen, Newbery Honor author Amy Timberlake takes readers on a second adventure in the new series reviewers have called an instant classic, with comparisons to Frog and Toad, Winnie-the-Pooh and The Wind in the Willows.
