Alex M Brandt – I'm very grateful for your positive review, Chukwuka. Like you, I get worried about sequels. Particularly the middle book in a trilogy, which so often seem to sag as they as they pack in all sorts of filler material to bridge the gap to the next in the series. And SciFi seems to be the worst genre of all for this. I did a lot of work on the story line to avoid the problem, so you can imagine how pleased I am to read your comments.
Chukwuka Osakwe – @peterwatson I was really pleased with it. I could feel myself holding my breath initially when I started reading it. Really can't wait for the third book. Merry Christmas!
