This is one of the Quick Reads series of Doctor Who novels, and features the Tenth Doctor (as portrayed by David Tennant) with Rose. Just a little over 100 pages long, this quick read is definitely that; but it's a great story.
The Doctor and Rose land on the Moon; only it's not the Moon, and the Tardis is trying to tell the Doctor something. Not far away, an archaeological dig has found something quite wrong in some Roman ruins. And that's only the beginning.
This is a really good story, full of great Doctor Who action and characters, and of course Daleks. Definitely recommended.
