The American Roller Coaster is by Scott Rutherford, and for my money is the best out there. It really has a great layout, and takes you through coaster history, construction, and building booms - great for the non-engineer! I'm looking to buy the coaster book that has Mantis (CP) on the cover, but I haven't been able to find it yet.  I've seen it on eBay, but not at a really good price.
