What a very cool concept! Wholly original and incredibly interesting. I didn't know it was a series when I started but I'm really glad it is because i definitely want to know so much more about these characters and their worlds! Thanks to Bloomsbury for the review copy!! I got so invested in the end and there were some great twists and surprises. Can't wait to learn about about X and The Lowlands! 
 Full review as originally posted HERE on The Book Addict's Guide 1/11/17: I was fortunate enough to read THE EDGE OF EVERYTHING incredibly early when Bloomsbury asked me to include a blurb for the ARC! (Eee!) it's a weird thing to sit on a review for half a year but I knew I had to write some things down after reading, otherwise I'd never be able to form coherent thoughts when reviewing! 
 THE EDGE OF EVERYTHING was a really unique novel for me. If you're looking for a feel, I'd thrown out EVERNEATH by Brodi Ashton (the Underworld aspect) meets DAUGHTER OF SMOKE AND BONE by Laini Taylor (the forbidden romance). THE EDGE OF EVERYTHING is about Zoe, the quirky yet girl-next-door type who meets a bounty hunter from hell -- literally. When Zoe meets X, her entire world is turned upside down in so many ways and it was incredibly interesting to see the ways that she and her family were affected by X's appearance. 
 The book started off a little slow for me, but not in a bad way. X appears on the scene and Zoe can clearly see that he's not quite human so after the first few chapters, the first half of the book is a lot more character development and set-up before it hits some of that world-building that I love. The delay in action really had me focused on the characters and their clear pull towards each other which was definitely important for some plot points down the road! It was also a bit slower, I think, because the concept took a bit of figuring out. This really wasn't like many books I've read before so I was trying to place it into a genre (Fantasy? Paranormal? Mystery?) and figure out how everything really worked. My advice is to just let the book take you where it will and don't try to put this one in a box! There are lots of elements at work and things came together really well in the second half of the book! 
 I was hoping for a bit more world-building regarding the Lowlands earlier on the book but I'm such a sucker for that kind of stuff that I was just dying to know what it was all about. It's not quite Hell or the Underworld as we "know" it so I was so curious to explore the different rules and regulations, functionality, and why it was so important in Zoe's story line. There was a lot to explore there and I was curious to investigate this dark side and how it maintained balance in the world. I will admit that I was hoping for a bit more in this book BUT there is still a lot to explore in upcoming novels which I'm pretty excited for! 
 I didn't know this was a series when I started since I read it so early but I'm actually really glad it is! Once I really got into the book, I was so curious about really everything and I couldn't wait to see what happened next! There's so much more exploring that I want to do and I'm really excited to see where Jeff Giles takes his readers. I see so much potential for even more development and I can't wait to see where this story goes!
