A magical junkyard, a gentle Sea Serpent teacher, and an underwater adventure where real ocean science comes alive. A fast, page-turning adventure for readers ages 7–10.

Eli and his sister Grace never planned on meeting a Sea Serpent. But when Uncle Larry’s junkyard door swings open to another world, they plunge into an underwater adventure where science comes alive!

Guided by Shel—a gentle Sea Serpent and marine biologist—the kids explore coral reefs, encounter strange sea creatures like spiky pufferfish, blobfish, and even a swirling Tuna Tornado. But their biggest challenge lurks in the deep: a sixty-foot Megalodon blocking their way home. To escape before the portal closes forever, Eli and Grace must complete every task and discover the ocean’s secrets.

Packed with action, cliffhanger chapters, and real marine science, Sea Serpent of Science is the perfect choice for reluctant readers and kids who crave fast-paced, exciting adventure.
