Win a signed copy of #TheAthollExpedition on Twitter

I have a few copies of The Atholl Expedition going spare and thought I would run a competition to give one away to a worthy reader! The competition will run for seven days, at the end of which a winner will be picked at random. Here are the rules:

Reweet the competition message which can be found here.Follow me on Twitter here.At the end of the competition week I shall select a random winner and DM them to ask for postage details.Quite a few people have entered already so get retweeting for a chance to win! You only need to enter once - tweeting it multiple times won't give you a higher likelihood of winning.
For those of you who aren't on Twitter, don't despair. I am planning a Goodreads giveaway in the near future as well.
