This is a great steampunk genre adventure involving one George Dower.
Although his father was a genius at the clock work skills, not much of that rubbed off on George.
Having inherited his fathers clock shop George is more or less trying to cruise along on his fathers reputation, without actually doing anything.
In rapid succession George is presented with a super complex clockwork mechanism to fix and almost immediately someone tries to steal it. George is then off on an adventure that soon includes some pretty weird people, religious zealots, aristocratic geniuses, time travel, aliens on and around Earth and an uncertainty as to who is the bad guy and who the good guy.
All in all, a smooth flow of peril and escape plus a cast of most curious characters keeps the action flowing and the readers interest high.
A great adventure and a great read, which has prompted me to order his next book called Morlock Night.
