The 3rd revised edition of my book "Some Adventures in Euclidean Geometry" focuses on involving the reader in the mathematical processes of discovery, conjecturing, proof, refutation, classifying, etc. It covers many classical geometry results ranging from the Euler line, Napoleon and Van Aubel's theorems, the Fermat point, etc., as well as several new generalizations and results. Many of these are useful for enrichment and further exploration as well as preparation for mathematics competitions.
