Seventeen years old and agoraphobic, Psyche Middleton vows her dad will never see the risqué photos she took during a summer modeling stint abroad, but one of them ends up on a billboard in her Montana hometown. Now everyone—especially her dad—can see it. And yet, somehow, those are the mundane things in her life because she is about to fall unexpectedly, head-over-heels in love with Erik, a mysterious young man who rescues her from a crowd of admirers, and who she’s never actually seen because…he can make himself invisible.

As strange as this may seem, it’s about to get even stranger. Erik takes her to his palace in an idyllic kingdom, and she is swept into the beauty and culture of his world, but his affection has one condition: she may not see him. Overtaken, intrigued, and still not wholeheartedly believing he’s real, Psyche is going to have to decide if she can love him blindly; because if she can’t, she may lose him forever.
