Ace has been away from the TARDIS for three years when events and time conspire to make her desire to return to the Doctor. Using a piece of technology, she links to the TARDIS, but one much changed from her time there: the Doctor has lost his memory and Benny is in hiding for her own safety...This book is a bit of a worry. It's purpose appears to simply be to return Ace to the TARDIS crew and to tell a mildly Dalek-related story (odd, since Virgin didn't have the rights to use the Daleks in their books...). It also features Absolom Daak, a charcter from the Doctor Who comic series, who is a Dalek Killer!Despite all these Dalek-related issues, the story has little to do with them. Instead we are served up what amounts to a generic Who opponent, who is defeated in a generic Who way.A lack of true creativity dooms this book to being, at best, a second-string novel in the long line.
