My first thought is that I would have read more of the story of these two men. In fact, I just wish there was more all around. More of the desert settlement, more of the Technicians, more of little Athena, more of London, just MORE. *LOL*
I enjoyed the two main characters, Asher and Gabriel. I liked what I perceived to be their age difference and I believed the chemistry between them, even though I would have liked more about how that developed. :)
I've now read two of Cornelia Grey's novels and this novella and I can honestly say that I really enjoy her writing. One thing to mention is that there's always a little bit of humour no matter how dire the situation and I totally appreciate that.
I would have given this 4 stars except that I found in the couple of scenes prior to the climax of the story were given a bit of short shrift. I needed more fleshing out of the motivations of both Asher and Gabriel leading to the climax of the story.
All in all, a good, fun read. :)
