Steampunk superheroes seem to be all the rage lately and with great books like The Kerberos Club, I can see why. My only quibble, and I guess it's really more a request (vain hope) for a web supplement giving more details or examples of the challenge a prospective club member must go through before being accepted. Yeah... that'd be cool.
Otherwise if you like Mark Hodder's Burton and Swinburne novels, or Jonathon Barnes' excellent The Somnambulist, or even Andrew P. Mayer's Society of Steam novels, you owe it to yourself to get this book.
