Hi,
skeptic_UK. Welcome to the forum.
As mentioned, there's not much in the way of actual books debunking Apollo "hoax" claims. At one point, NASA actually was going to pony up $15k towards a book written by engineer and author James Oberg, but it was ridiculed as a waste of money and scuttled.
If you'd like to learn about Project Apollo in context, and in detail, you could do worse than to peruse the wealth of material to be found at the
NASA History Office and at the
NASA Technical Reports Server. There is enough material there to keep you occupied until, conservatively speaking, the end of time. So feel free to ask for guidance on particular topics or themes in which you're interested.
Jay's
Clavius site and Bob's
Rocket and Space Technology are two excellent and concise sources discussing Apollo hoax claims. Other members here have produced other hoax-related materials, although I am rather deficient in remembering who's created what. But please take a look and ask for help finding what you're interested in. You may also want to peruse threads here and at this site's immediate precursor,
the Proboards site, to get an idea of common hoax claims and rebuttals to same.
Personally, I think you'll find this a congenial site if you continue along the open and civil approach with which you began. The AwE130 thread was a bit of train-wreck as frustration with AwE130's self-important dishonesty boiled over. Anyway, nice to have you on board and looking forward to a fruitful discussion if you choose to participate.
