Winter break is over, and it’s another five months until summer vacation! A.J. and his friends aren’t looking forward to school starting back up, but they’re even less excited when Dr. Carbles, president of the Board of Education, cancels ALL school holidays. No Presidents' Day, no Memorial Day, and forget about any snow days. Morale is down, but Mrs. Roopy, the librarian, has a trick up her sleeve. Instead of celebrating traditional holidays, the school will celebrate real holidays that no one has ever heard of! Will the kids be able to save the year with their fun festivities or will Dr. Carbles’s anti-holiday agenda win out?
