David loves school! Especially since he just won third place in his school’s science fair AND his class has entered the regional Faith & Fun Science Fair!

It’ll cost $500 for their class to go to regionals, and David is ready to be the top fundraiser and make it happen. The only thing standing in his way is Abby, the new girl who seems to be good at everything and keeps stealing David’s thunder.

Can David stop Abby from sabotaging his chances of being discovered as a scientific genius? And when someone steals their fundraising money, can he figure out who’s sabotaging his entire class?
