"The Splendid Baron Submarine is delightfully absurd, imaginative, and fun—a wonderful book for middleschool children to read on their own, and an even better book for families to read aloud together." - Foreword Reviews, Starred Review

Pirate treasure? A top secret mission? A terribly rude monkey with personal boundary and hygiene issues? Two out of three of those things sound like a dream come true to the young, clumsy, and terribly unscientific Waldo "W.B." Baron, when his clever inventor parents are hired to go on a secret treasure hunt. The Baron family dives into adventure with their steam-powered submarine, but they aren't prepared for the complications that occur during their trip, which include shark attacks, deep sea diving mishaps, and even a pirate's curse, all of which W.B. is lucky enough to discover, one stumble, trip, and fall at a time.
