I would probably have to say Obsidian by Jennifer L. Armentrout. I heard SOOOO much about this book and every single person absolutely loved it. I honestly thought it was too good to be true, but it really was worth all the buzz. I completely adore this series and am so happy I have finally read it. This novel is the exact reason why I listen and follow the buzz, because if I didn't I honestly would have never picked this novel up. Aliens just didn't seem like my cup of tea.
