Hello Everyone,
My book was out last month, but I just figured out that I never posted about it here 
You can learn more about what is covered and get it from several places, but the most common ones are:

http://www.amazon.co.uk/Learning-Unreal%C2%AE-Engine-Game-Development-ebook/dp/B00U64KQM2
I hope you like it and get learning some stuff with it.
