When Gid Ralston confidently declares that his paper bridge could hold a refrigerator, his friends are not so sure. What begins as a hilarious school challenge becomes an unforgettable engineering adventure as Gid, Tess, Bram, and June test, fail, rebuild, and discover why clever design matters more than impressive looks. With Axo offering useful clues-and plenty of humor-the team learns how shape, support, patience, observation, and teamwork can transform flimsy paper into something surprisingly strong. When a sudden storm adds one more unexpected challenge, Gid discovers something even more valuable: real strength comes from learning, adapting, working together, and knowing when to stop.
