I wish I knew why I kept reading these. Neither the sci fi or the erotica part are great, but I keep hoping they will be what I want them to be. 
 The characters are 1 dimensional and predictable. The problem is that in each book, she teases the next book's characters so well that I just want to know what's going to happen to them. And so, I will read the 4th one and finish out the series.
