I've read several of the new Doctor Who books, and this one is by far my favorite. The dialog, especially that of the Doctor, rings very true. One scene in particular is very strong - toward the beginning when the TARDIS is in trouble (what else is new). I could picture the Doctor running in circles around the console, hear Tennant's voice in my head. The words were perfect.
OK, the story is a little sparse. But it's a good one day read.
This Doctor Who book rang true to the Doctor's personality but the writing was rather choppy. Rose was a bit like herself. The story line just seemed odd and kinda thrown out there in spots. Still a good story though.
