I can't say enough about Hellbound. This is a graphic novel that is absolutely batshit crazy, with no predictable moments and great characters. The artwork and creature design is phenomenal, as are the plot and writing.
Two FBI agents, Agent Brew and Agent Mirchandani, are not department favorites. As a result, they have to deal with all the weird cases that nobody else will touch. This means the cases that will most likely never be solved, the gory cases, and the downright occult cases (which they don't realize are paranormal at the time). They are called into a small town for a case that is totally out of the scope of the local police force. While investigating, they encounter a werewolf, which bites Agent Mirchandani when the Agents get in between Dusker and the werewolf. Dusker is an obscurer, one of a line of ancient guardians that keep the monsters in check. His adversary, Marion, chooses to mount a full-scale attack on Dusker and the Agents.
The final showdown is fantastic! There are more tidbits on the complicated history between the obscurers and the monsters, as well as a plethora of extremely creative and detailed monsters. (One of my favorites has to be the tree-root thing with a huge eye and a cemetery growing out of it's shoulders. It may not sound like much, but it's really a sight to behold!)
The ending is aggravating, but only because I wanted to know what happened next. The pages flew by, and before I knew it, it was all over. I'm hoping there's another (several) volumes, because this is a story I'm extremely interested in following.
