Nat Boyd and his best friend Boyd Fink are about to spend a week at Camp Willomet. No homework, no parents.only bunk beds, bonfires, and toasted marshmallows. Neither Boyd can wait to go! But four days before camp starts, Fink comes down with a case of polka-dotted tonsils. Nat's got all his fingers and toes crossed, hoping Fink will make a speedy recovery. Otherwise, Nat will face Camp Willomet on his own, and there's no telling what might happen!
