It was only OK. A slow start that didn't grab me, but I persisted and the novel improved with more stuff happening, approximately starting with the second half of the book. Definitely not enough action (except towards the end) and too much in the character's head for my tastes. For such a slow start, the story wrapped up pretty quick, too quick. A lot of scenes seemed like filler, making the first half of the book even more boring and could have been skipped if the book had tighter editing. Descriptions, style of writing were great, dialogue only so-so (not always believable imo). I liked the concepts also. I didn't care for this book in particular, but with the skillful writing and creative ideas, I am definitely going to give this author another try. I prefer a lot of action in my books and I do prefer hard science fiction, which this is not, For those who like to be in a character's head, there is a lot of that here.
