Some things are better together. Like peanut butter and jelly. Or Annie and Jason. So when her best friend's house is threatened with foreclosure, Annie Jenkins is bursting with ideas to save Jason's home. She could sell her appendix on eBay. (Why not?) Win the lottery. (It's worth a shot!). Face the evil bankers herself. (She's one tough cookie, after all.) Or hunt down an elusive (and questionably real) pirate treasure. Whatever the plan, it has to work, or this is undoubtedly THE LAST GREAT ADVENTURE OF THE PB&J SOCIETY.
