Good sequel, not keen on the narrator.

My 11 year old daughter loved Cogheart and was eager to start the second book in the series, Moonlocket. It's not as good as the first one, and gets off to quite a slow start - however the story does get more exciting in the second half of the book. We read the first few chapters together, but decided to buy the audio book to listen to in the car to speed things up - and that was a huge mistake. My daughter says the narrator sounds like a robot, and reads the book in a manner one would use to read picture books to toddlers. She makes the two main characters sound like they are five years old. The narrator also has a peculiar reading style, pronounces the odd word incorrectly and pauses in strange places within sentences. My daughter has decided that the audio version is simply not enjoyable and we have reverted to reading the book ourselves.
