"Upbeat and chirpy, and decorated with lots of kid-style illustrations, Leo evokes sympathy with a light touch." -- School Library Journal (starred review) The joys and trials of fourth grade --and of life with her father now that her mother is gone -- play out in charming letters from Annie to her dog, Leo. Genuine and funny, Amy Hest's first-person narration revisits a winning young character as she takes on a new year -- and a new dog -- with humor, honesty, and resilience.
