The clash of ancient rules and modern expectations swirl together in this cool, urban 21st century faery tale. Rule #3: Don't stare at invisible faeries. Aislinn has always seen faeries. Powerful and dangerous, they walk hidden in the mortal world, and would blind her if they knew of her Sight. 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 and 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! Suddenly none of the rules that have kept Aislinn safe are working any more, and everything is on the line: her freedom; her best friend, Seth; her life; everything.
