Just how humdrum is 10-year-old Aldo Zelnick's life right now? So humdrum that he sets out to measure which January day will be the most boring. So humdrum that Jack and Bee succeed in getting him to try some weird hobbies. So humdrum that his recurring Hawaiian dream has become way more enticing than real life. So humdrum that even unathletic Aldo agrees to downhill ski with his superjock brother, Timothy -- and finds that hotdogging it on the slopes can be hazardous to your health. The humorous plot and lively drawings in this book will captivate enthusiastic and reluctant readers alike. This eighth installment in an A-to-Z alphabet series also includes a glossary of fun and challenging "H words," such as harbinger, hyperbole, and hogwash.
