For those seeking a good geometry book, "Algebraic Geometry" by Hartshorne is mentioned, but further clarification on the type of geometry needed is encouraged. "Geometry" by Serge Lang is recommended as a solid high school-level text that avoids unnecessary complexities. "Introduction to Geometry" by Coxeter offers a broad overview but is not suitable as a first book. Euclid's "Elements" is highlighted as a foundational text, though it contains some errors. For math contest preparation, starting with Euclidean geometry and considering Harold Jacobs' book is suggested.
