Ravenous 4

The Ravenous are the most relentlessly voracious creatures ever to haunt a Time Lord, and they now have the Doctor’s scent. The only thing left to do is stand and fight. It will take a monster to defeat a monster. But what will be the cost?

The past, the present, and the future conspire against the Doctor as he fights to defeat the only creature ever to strike fear into the hearts of a Time Lord.
