Wicked Lovely by Melissa Marr
Now this is what I'm talking about! Wicked Lovely is an incredible debut that combines contemporary themes and historical fantasy. Aislinn has always been able to see faeries, they have pervaded her life with their hedonistic and often terrifying ways. Now she has been targeted as the new Summer Queen by Keenan. Keenan is the gorgeous Summer King who has been searching for 900 years for his co-ruler. What nobody bargains for is Aislinn's great strength, personal resolve to maintain her mortal life, and her love of a mortal. Takes the old girl-hopelessly-falls-for-immortal-and-needs-rescuing and turns it on its head!
