Monster Hunter Nemesis by Larry Correia

Agent Franks is a monster, literally.  He's made from various human parts (just like Frankenstein) and he has a magic elixir he uses to heal his wounds and keep fighting.  He also contains a spirit from long ago.  He's on the right side, helping keep the world of humans safe and honoring an agreement he made long, long ago.  One of the items in the agreement was that they would NOT create any more creatures like him.  Then the government broke the contract by experimenting with more monsters...

Baen and Edelweiss allowed me to read this book for review (thank you).  It will be published in July.  If you've been waiting for the next book, it's here!  This is the fifth book in this series and the only one I've read.  That didn't make it hard to read or understand.  I also found it fascinating.

This is story of war between demons.  In the beginning, it was a story of a power play by the government, but they knew not what they created.  Nor did they realize the time bomb in the monsters head's could be neutralized.  There was so much they didn't know...

The battles are stupendous, lots of humans die along with a few demons and I learned these battles had been ongoing since the creation of earth.  I wouldn't want to fight the right hand of Lucifer, would you?

There are surprises along the way (like when Franks finds out he's a father) and the ending is ironic and gives you a clue to the next book in the series.  

What I liked was how Franks, who's like a machine and has no emotions, finds out that he can feel loss even if he can't feel sorrow.  He also doesn't want his friends hurt.  The longer he spends with humans, the more they rub off on him.  I think this is a good thing, but it might not be handy when fighting monsters.  I guess we'll see when the next book comes out!
