Applewhites at Wit's End :
When the famously artistic Applewhites fall on hard times, they turn their sixteen-acre home, Wit's End, into Eureka!, a summer camp for creative children. It seems like a good idea. . . .
But amid the ordinary chaos of temperamental artists and headstrong campers, anonymous, threatening notes begin to appear in the Applewhites' mailbox. As the only two level-headed ones in the bunch, E.D. Applewhite and Jake Semple are determined to get to the bottom of things. Will they be able to save the camp - and the family - from disaster?
