I have to totally disagree with the previous reviewer. This was the first of the First Contact series that I read (some 7 years ago), and after that I was hooked. The story line was excellent and easy to follow and the main characters are SO likeable. Despite the fact that I hadn't read either of the first two books, I still knew exactly what was going on. The plot isn't so sophisticated as the first book, and does tend to get a bit ridiculous at times, but as long as you take it with a good dose of humour, it's a good read.
This is one of my favourite books and I'm very much looking forward to reading it again!
