Paige and Paxton are determined to help their friend Penelope find her perfect fit. In Puzzleland, every puzzle piece is different, and each has a perfect fit, something he or she loves to do. Paige and Paxton have already discovered theirs, so they turn their attention to Penelope.

When Papa Puzzle and his engineering cousins offer to help, Paige and Paxton are skeptical. But as the engineers explain the many ways they shape the world around them, Penelope begins to see engineering in a whole new light.

From buildings, bridges, and airplanes to cities and the products we use every day, engineers help make modern life possible. In the end, Penelope not only finds her perfect fit, but the three friends also discover an important engineering lesson: there is often more than one way to solve a problem.

Part of the STEM Adventures with Paige & Paxton series, this engaging adventure introduces children to fundamental STEM principles through the experiences of adorable puzzle piece characters who live, work, and play in the puzzle-shaped island nation of Puzzleland.
