Time Travel

Okay, so I'm going for it - the time travel novel, and all the head banging pitfalls that come with it! I've been playing around with an idea for a couple of years now, and I've finally got started on it - it's taken me until now to work out who my murderer is going to be! Now that's done, I've got piece the puzzle together and get to the end of the story - without a picture on the box lid! Wish me luck - I'm going to need it!
