I thought the concept for this novel was extremely interesting, and I was not disappointed. Ewan leaves a few things unfinished, but I am not sure if he places to write more about Charlie Howard. I would certainly read it. As for not wrapping some of it up - it certainly does not detract from the excellently written story. Ewan gives enough information to make you think you've figured it out, but never enough to give it away. Even if he doesn't write about Charlie again, he is on my list of authors to watch.
