About this listen

A perplexing task. A mystery to solve. Can a scientist-in-the-making find the answers hiding in plain sight?

Twelve-year-old Putney Hicks is gearing up for her school's cardboard-boat regatta, but excitement soars when she rescues a neighbor's dog from a rip current. Disaster looms as team draws pit her against her arch-rival, Sue. As tensions rise, Putney must prove her innovative design concept in a pre-race challenge within an alligator-infested lagoon.

Armed with her magical tablet and AI companion, Sam, can she stay afloat amidst the chaos? Can these adversaries set aside their differences to build a cardboard boat that truly floats? Could the mysterious swamp creatures hold the solution to their greatest challenge?

The Buoyancy Project is the brilliant second book in the Putney Hicks Inventor Adventures series—a clever, science-driven adventure combining hands-on problem-solving with daring escapades. Perfect for fans of strong female leads, STEM challenges, and stories brimming with imagination and heart. Ready to dive in?

Buy The Buoyancy Project now and sail full STEM ahead on Putney’s next unforgettable adventure!
