Query: A great "what if" type of book,very interesting

I was first introduced to the 6 book series with this book..i usually read lots of magazines..im not much of a book reader..but this i could not put down..some scenes can be a little vulgar and graphic but it is still a great book..i urge you to read the entire series..it is worth it..and at only 2 bucks a book..what a minimal investment to so much entertainment
