"Only Human" - Gareth Roberts

Another Doctor Who novel, this one featuring the Ninth Doctor and Rose. Just when I was losing faith in Doctor Who novels, resigning myself to not reading every last one... here is probably the best I've read. It has renewed my faith. Not only does it have the Ninth Doctor at his clever and sarcastic best, but Captain Jack is along for the ride. The author captures Jack's insouciance and constant flirting with ease. Also we have an intriguing plot involving illicit use of a "rip engine" for travelling back to prehistoric earth. The challenges our heroes face add just the right amount of danger. Good plotting, nicely drawn characters, believable difficulties.
