I'm glad that I gave in and read the third book as well. It was definitely more enjoyable than the first two. Kate was a funny and smart character and the relationship between the three moved along at a believable pace. The ‘light’ and ‘dark’ twin was maybe a little over the top, but it still worked. I also liked the story setting more, different planets and a lot more about the Scourge. It was an enjoyable smut book with a lot of drama, a little too much drama for my tastes, but oh well. All was eventually fixed by a major deus ex machina. But still better than the first two.
