Obsidian by Jennifer L. Armentrout
I don't read many sci-fi books, this being the first in a long long time. Thanks to this book, this won't be the last either. I was really impressed with every aspect of this book, the writing, the imagery, the plot and the characters.
Katy, a quiet, book blogger is the new kid in town. She moves in, with her single mother next to a mysterious brother and sister, Daemon and Dee, who she can't quite work out. Dee is an overly friendly, even clingy, best friend and Daemon is, well, a bit of a dick. As Katy spends more and more time with Dee, Daemon is always there telling her to back off and Katy can't quite understand why. I'd say it's a spoiler to reveal why Daemon is the way he is towards Katy, as I spent half the book dying to know why he didn't really seem human, so I won't give anything away.
This book is intriguing, sexy and infuriating. Throughout most of the book, I hated Daemon, but at the same time I wanted him to kiss Katy and never stop. The plot is fairly realistic considering its a sci-fi novel and I could really imagine everything happening, rather than some books that just seem ridiculous. I will definitely be reading the other books in the series when I get chance and I think you should too.
