"The short, sad life of Tooley Graham was over," doesn't sound like a happy conclusion but is pitch perfect in this short, simple and endearing middle-grade novel that follows on the heels of The Small Adeventure of Popeye and Elvis (2009). Owen Jester is focused on several things during his summer vacation: finding a way to keep his trapped "pet" bullfrog alive and happy, locating what fell off a train with a loud crash! one night and keeping annoying next-door neighbor Viola—who knows everything—out of their business as he schemes with his two best friends, Stumpy and Travis. The discovery of a sleek, red two-person submarine in the brush alongside the tracks changes everything. Can three young, girl-hating boys and a willing and very able—and tolerant—girl move a submarine to Graham Pond? If they manage that, will they ever be able to pilot it? In the heat of a languid Georgia summer vacation, in the dreams of irrepressible youth, anything is possible. O'Connor has spun a lovely read that perfectly captures the schemes and plans of school-age kids in the long days of summer. (Fiction. 8-11)
