The title characters of Lenny and Mel return with more silly shenanigans in this jocular account of Lenny and Mel's Summer Vacation by Erik P. Kraft. ""Too bad camp wouldn't take you back.... They'd have plenty for you to do,"" says the twins' father when he finds them loafing around the living room. They do a stint at an animal shelter and the library before setting out with their parents and grandmother to a cabin so tiny that only one of the three sleeper couches can open up into a bed. Kid-like drawings echo the siblings' inane sense of humor, adding to the caper's goofy good fun.
