The Adventures of Big Bertha: The Birthday Camp Out

By Abby Brixius

It's Auggie and Stella's birthday-and someone's stealing the party

Around every turn things begin to disappear. But then the presents vanish

The Yeti family needs to solve this mystery fast, or there won't be a party left to celebrate.

Join this big-hearted, fuzzy family (two moms, one grandpa, two silly kids, and their rumbly van Big Bertha) as they track down the sneaky thief and discover that kindness-and a good laugh-can save any celebration.

Perfect for fans of mystery, family adventures, and birthdays that don't go quite as planned.
