the 4th one is good. i am getting the 5th one as soon as i can, and get her 3rd series and read them. one of my guy coworkers is reading the GK series. he picked up my kidle and was browsing my books and i looked over and he started reading the 4th one and i told him if he's gonna read them to start at the begining. i am gonna tell him to read VA next.
