The Integral Trees

*The Integral Trees* is a science fiction novel by Larry Niven set in a unique environment called the "Tree," a vast, buoyant, hollow starship where gravity is generated by its shape and internal mass distribution. In this setting, inhabitants experience gravity in all directions, creating a floating, tree-like space. The story follows characters navigating survival, relationships, and the environment’s physics. The novel explores how life adapts to this unusual, gravity-manipulating habitat, blending imaginative science with human emotion in a science-driven universe.
