A predictable middle grade adventure that will find fans among steampunk aficionados.

I found the plot very by the numbers (except for the big reveal about the cogheart). The villains are classic mustache-twirling evil doers with no depth. I liked the mechanical characters the best.

Recommended for fans of A Series of Unfortunate Events. This book may be a little scary for little kids, so I'd stick with middle graders.

Spoiler

: I did find it very unfair that Lily regained her father (that was obviously going to happen from the beginning) but Robert lost his.

I read an advance reader copy of Cogheart from Netgalley.
