Doctor Who #4 from IDW Comics. This was not available in the UK due to (yet) another licensing dispute! Get it here otherwise you are going to have to find one in the US and then pay airmail to get it imported...

Someone or something is removing the populations of entire planets. The Doctor and Martha must find out who, what and why, or Earth will be next! With art courtesy of Nick Roche (The Transformers) and words by BBC Doctor Who show story editor Gary Russell!
