This book is fine. It has a decent premise, fun set-pieces, good ideas, flashes of great character work, and is very silly. I enjoyed myself thoroughly while reading it. The problem is is that beyond the surface there just isn't much going on in it. It's a fun Doctor Who adventure and nothing else. The most damning part of it all is I forgot I'd even read it. It just left my brain until I was checking my bookshelf and went "Oh yeah that one".

So it's fine. If you read it you'll probably have fun with it, but don't go rushing out to grab a copy.
