Wicked Lovely by Melissa Marr

Rule #3: Don't stare at invisible faeries.
Aislinn has always seen faeries. Powerful and dangerous, they walk hidden in mortal world. Aislinn fears their cruelty—especially if they learn of her Sight—and wishes she were as blind to their presence as other teens.
Rule #2: Don't speak to invisible faeries.
Now faeries are stalking her. One of them, Keenan, who is equal parts terrifying and alluring, is trying to talk to her, asking questions Aislinn is afraid to answer.
Rule #1: Don't ever attract their attention.
But it's too late. Keenan is the Summer King who has sought his queen for nine centuries. Without her, summer itself will perish. He is determined that Aislinn will become the Summer Queen at any cost—regardless of her plans or desires.
Suddenly none of the rules that have kept Aislinn safe are working anymore, and everything is on the line: her freedom; her best friend, Seth; her life; everything.
Faerie intrigue, mortal love, and the clash of ancient rules and modern expectations swirl together in Melissa Marr's stunning 21st century faery tale.

This book was my first real introduction to modern day faeries, and what an introduction it was. I devoured this book! Marr's description of the faeries had me feeling as if I myself could see them. The world was complex and I loved that she included so many different types of faeries, each having a different look, personality and history. I loved the sharp contrast between the Winter Queen and Winter Girl and the Summer King and Summer Girls...the descriptions of the biting, icy cold breath of the Winter Queen gave me chills.

I found myself being more drawn to Keenan and Donia while reading this book, as opposed to Aislinn who is the main character. Perhaps it is because they are each so full of angst and have a complicated and tortured history. It made me really care about what was going to happen to them, and eager for each one to have their 'shining moment.' As for Seth, I liked him but finished the novel feeling like I didn't really know him. I have a feeling we're going to learn a lot more in Fragile Eternity, however, and am anxiously awaiting its release!
