I have a book I bet no one here has ever heard of:
The Beast Hunter: A Keltin Moore Adventure by Lindsay Schopfer
The story takes place in a sort of 19th century steampunk type of setting. The main character, Keltin Moore, hunts beasts for a living. We're not talking wolves or bears or whatever; we're talking nightmarish creatures straight out of the realm of the Horrorterrors netherworld, amalgamations of body parts that should never be combined (like tentacles and pigs).
The atmosphere is very serious, a cold, harsh world. The book and its sequel Into the North, are frightfully descriptive, whether it's the beasts themselves or the unfortunate victims of them. A tale of hardships, guns, big scary things, and friends who are by your side to the end, this is a little known book you won't regret reading.
The book was self-published by the author, which is why very few people know about it. My family knows him pretty well, and one of my really good friends painted the cover. There's nothing cooler than knowing people like them. It's books like this one that inspire me to sit down and write.
