Through the In Between, Hell Awaits is a wicked tale of demons chasing each other from the In Between to Earth and back. The In Between is effectively the passage to Hell, and even though Hell is in the title, the book never actually gets there. Still, it doesn't really matter. The In Between is Hell enough.
Austin and Audrey get caught up in the impending war between rivals Baz and Dagana. Both want to rule the In Between with absolute power, but neither wants to give in to the other. Dagana in particular so desperately lusts for power that she does anything she can to get it. This includes collecting suitable humans to transform into her demon pawns. She hopes to bring an army back to the In Between to completely take over.
The story shifts between Earth and the In Between. Both have a life of their own and both are equally important to the tale. The only part that can be disorienting is the name changes as the demons move from world to world (a couple characters have at least three different names). Thankfully, there are not so many characters that you can't sort it out pretty quick.
All in all, I really dug the book. It was graphic, violent, and had a really cool feel to it. The only thing holding it back from a higher rating is no fault of the author. It's the editing. More times than I could count, I found myself wanting to grab a red pen and go to town. This is particularly unfortunate because it could have turned a good book into a great one.
Don't let that stop you from reading it though, because it really is a hell of a book. Just suppress your inner editor and enjoy the ride. It's worth it.
