Rather to my surprise, actually, since I almost-to-never win anything, and I had no idea I was taking part in a contest!
It turns out the contest was being run by fellow author Anne Brooke to promote her latest book launch at Riptide, a new(ish) publisher specialising in gay fiction. I commented on one of Anne's blog posts to congratulate her on the new release and hey presto! the very next day she told me I'd won the contest and could choose any book from her impressive back list.
The one I've selected is called The Bones of Summer and is a gay mystery thriller involving missing persons, amnesia and a disastrous past love affair. Oooh-er. It sounds right up my street and I'm very much looking forward to reading it.
