free kindle book - 22nd May

Hi
To celebrate the upcoming launch of my second short sci fi collection, I'm putting my first collection up for free on the 22nd of May.   It's the last time I'm giving it away, so grab it while it's going (and leave a lovely review if you feel like it).  Link to Kindle store below - thanks:
