Lunch Lady 2-for-1 special

"Lunch Lady has villains to fight at school and camp in this action-packed book. First, Dee, Terrence, and Hector come face to face with a very special guest on Author Visit Day--but there's something a little off about the world-famous writer. What evil designs does he have on his agenda? Then, the kids take a sigh of relief and are relaxing at summer camp. What evils could befall them there? Of course, there is the legendary swamp monster. Stories say he haunts the camp at night. But that's just a legend. Or is it?"--Provided by publisher.
