Soon-to-be fourth-grader Mason Dixon does not want a pet, but his parents think it will be good for him. Goldfish dies soon after his arrival (from overfeeding). Mason is relieved. Hamster escapes. Mason is relieved. Cat has to go back because best friend Brody is too allergic to ever be at their house while Cat is there. Mason is relieved. But when Dog comes, it takes a little dose of jealousy for Mason to realize he does want a pet, all of his very own. Claudia Mills introduces a new, hilarious character in Mason, and each of the three books about him will feature both boys as they cope with a new experience; pitch-perfect for 8- to 10- year-old newly independent readers, the books will maintain a consistent page count and feature black-and-while art throughout.
