The Jungle Gym Empire. The Foundation Chronicles, #7

As Leo (12) and Sophie (10) enter their peak activity years, Sterling Ridge undergoes its most playful transformation yet. In The Jungle Gym Empire, Grant rejects store-bought sets to design and construct a professional-grade ninja warrior course and playground. It is a project of extreme scale, featuring custom steelwork and high-tension obstacles that push Grant's engineering skills to their limit.
However, as the structure rises, a bittersweet realization settles over the ridge: the children are growing faster than the concrete is curing. This build isn't just about play; it's a monument to a childhood that is beginning to sprint toward adolescence.
