What is the hardest geometry book you know?

runner23: What is the hardest geometry book you know?
I am going to teach myself geometry and I need to know what book to use. I am doing this because I will be a sophomore next year and want to test out of honors geometry. Then I can be a year ahead.
So what is the hardest geometry book you know that also teaches well that I can get at a library or for cheap at a book store???

I am very good at math so the book can be one from college classes

I suggest Analytic Geometry by Abraham Spitzbart and
Elements of Analytic Geometry by Clyde Love.

Both are very good college level geometry books. You can get them at abebooks.com or alibris.com
