It was really interesting while I was posting Nemesis how many people told me that Alan was becoming their favourite character. It made me quite happy, because in many ways he is my favourite as well because he's so deeply human and makes so many stupid mistakes. He's insecure and lashes out, he's a bully, he hurts people... but that's what makes him so real to me. As far as character development goes, he's the one who has changed the most from the first chapter of Nemesis until the last.
I hear what you're saying about the fast-paced narrative. In truth, Alan and Matt deserve a whole novel all to themselves. Maybe one day that will happen, but for now this is the best I can do. I'm overflowing with ideas right now, both within the Nemesisverse and outside it. It's kind of doing my head in, actually.
Thank you for such a long and thoughtful review! I'm glad you enjoyed the story in spite of its shortcomings, and I'm glad the sex scene worked. I'm always afraid of making them too pornish. I probably read way too much fan fiction...
