Hello Shenghui,
Yes I cherish my copy of New Horizons In Geometry. I am blessed to have met Mamikon and to have known him while living in California and to visit him when he was working at CalTech. The color images in the book are priceless.
I bought Mamikon's New Horizons in Geometry and I am really impressed by the quality of the context. MAA press prints some most interesting math books in market IMO.
