Glad to see you picked up those books. I would recommend reading them in that order and also picking up the Passion Trap if you have not read it already (I did not read Solo Partner as some reviews I read indicated it seemed more geared toward a slightly older generation than ours but I believe the Passion Trap covers much of the same pursuer-distancer dynamic discussion).
I saw that review on Amazon too, and its very misleading -- the Passion Trap and The Solo Partner are very different books with different messages covering different situations. They're both worth reading, but one is not an updated version of the other.
