So, I have a friend who writes tie-in books for various geeky things, and he recently released a book called "The Case of the Claw" and it's set in a superhero world.
I have not yet read it! But I did ask my BFF, who did read it, what he thought of it and he informed me he was planning on giving it a 5 star review. SO! It's good! And Keith isn't paying me for doing this. I mostly want a LOT of people to read/buy it because I want to see the series continue.
Go forth and read!
