Doctor Who: The Tenth Doctor Archives — Titan Comics
Issue: #6
Friends, enemies and those slightly confused ones who fall between both have unwittingly colluded to bring something ancient, powerful and utterly devastating through from another plane of existence into the universe. And it's hungry - hungry for life. Literally. It eats life energy and reckons the Doctor and Martha could be its tastiest meal yet.
