I was really excited when I won this from FirstReads because 1) this book just sounded plain awesome, and 2) I won it right before I was about to buy it. So, I saved myself some money, which is an important thing since I'm addicted to books. Anyway...moving on to the review. This book was awesome! First, the writing was great. When I found out that this was Ms. Fine's first book, I was utterly blown away. This book reads like a seasoned author wrote this. That is truly an extraordinary feat, and I highly applaud Ms. Fine. Everything from the characters, to the world, to the dialogue was fantastic. I was immediately sucked into the story, and never wanted to stop reading. I actually read this during Hurricane Sandy, when my power was out, and I finished it in one sitting. But even if my power wasn't out, I wouldn't have been able to put this book down. 
 Let's start with the characters. Sanctum follows Lela, who is a badass heroine, that is snarky, sassy, strong-willed, and smart. She was a great main character, and I enjoyed reading about her. Her interaction with Malachi was brilliant, and could not be beat. I was literally screaming at the book for her to just kiss him already! Ms. Fine crafted a wonderful story for Lela. One that is filled with heartbreak and grief (over losing her best friend), but also courage and determination (to help her best friend). 
 Now onto Malachi....Malachi just about stole my heart. Luckily there was no love triangle in this series, and that made it all the better for multiple reasons. 1) Malachi could just about beat out any person vying for Lela's heart, and 2) I hate love triangles. Malachi is a brave, amazingly hot warrior that is a leader of sorts. However, he too is a badass, just like Lela. I loved how caring and compassionate Malachi was toward Lela. When he found out that something terrible happened to her in the past (and it was awful), he tried to help her overcome her fears, but never pressured her into anything. He was slow with her, despite his growing feelings. Everything about Malachi I absolutely loved, and can't wait to read more about him. 
 I honestly can't wait till the next book. Ms. Fine created a beautiful story, but also, and most importantly, this is a completely different story. There are no other books like it out there. Sure, it's about demons, if you want to call them that, but at the same time, it is something entirely new. And, trust me, it's genius. I highly recommend this book to everyone! I just need to find out when the second one is coming out (and hopefully it'll be soon)!
