What is the problem in the book No More Dead Dogs by Gordon Korman?

Wallace's problem is his unwavering policy of not lying. His parents divorced over his father's constant lying, so in a childish, single-minded decision, he decided that "honesty is not just the best policy; it's the only policy". Though this does not sound like a problem, the reader learns of many occasions when his truthfulness embarassed his mom. As an adolescent, his truthfulness hurts him both in the classroom, on the football field, and in his friendships. The first conflict is with his English teacher who gives him an F on a book review of "Old Shep, My Pal." Wallace thinks the book stinks because the dog dies at the end. Wallace is suspended from the football team until he writes a "satisfactory" book review for Mr. Fogelman. As the reader knows, that's not going to happen.
