This book would be nearly perfect if it contained any other Doctor/Companion combo. Or even just any other Doctor (Martha is too boring to really bother with either way). As it is, the Tenth Doctor is more of an annoying distraction than a hero or protagonist (as always), but he's landed in a fine, Ray Bradbury-ish October story that I quite liked. The alien/monsters are great, the setting and incidental characters are nice, and the atmosphere is perfect. And yes, author Morris did a very good job of capturing the (sigh) unique idiosyncracies of this incarnation of The Doctor. Sigh.
