I took a course in geometry which followed the Erlangen philosophy of geometry, which is to study geometries by their group of transformations. One book I thought was good was Transformation Geometry by Martin. There's also Geometry and Topology by Reid-Szendroi. Also, why not just read Euclid with Hartshorne's Geometry Euclid and Beyond?
