I havne't found book 3, but I wouldn't look for it, because in my personal opinion book 2 is a long step down. (I guess it was written by someone else to cash in on the first.) The first starts with capture and non-con but develops a loving relationship between the Dom and his first victim. (OK, that happens to be my favourite scenario.) The second is themed around the right of stepfathers and fathers to sexually enslave their daughters, and all the victims are pubescent virgins. If that's your thing...
