Wicked Lovely is the first novel in a series about a world where fairies and mortals intermingle. The story introduces Aislinn, a teen who can see the faeries around her, but who has been taught all her life to pretend not to see them. She is struggling to cope with the faeries when Keenan, the faery Summer King, enters her life and takes away her mortality, asking her to become the Summer Queen and defeat his mother, the Winter Queen. If she refuses, Winter will take over and kill all the summer faeries and mortals alike. However, Aislinn has no desire to become part of the faerie world, and is already in love with her best friend, Seth. In the end, she cannot avoid becoming the Summer Queen, and reigns alongside Keenan over the creatures she once feared. Upon defeating the Winter Queen, Aislinn brings peace to the world of fey. She also sticks with her best friend and new lover, Seth.
