The world of Fever Crumb is fascinating, and the author has done a fabulous job with the characters and the details. I didn't get sucked in like I expected to, though. I think it is a fabulous book, but I didn't love it. I do think that it will have a lot of big fans. I haven't read the Mortal Engines series, but I think I will have to give it a shot. (And, of course, I will want to read more about Fever's further adventures as they come out!) Reeve is a fabulous writer.
