Another ebook- Ninth Doctor

I'm back to my routine of reading one real book, then one ebook. After finishing The Chaperone, I read the ebook for the Ninth Doctor. The story was okay, I really liked how they revealed the companion gradually so that the reader didn't base their opinion about her on her appearance. I would have loved to see a Ninth Doctor story featuring Rose Tyler though, because I'm afraid the author of the Tenth Doctor's story will pick a different companion. But it was a pretty good story, no complaints!
