Sophia Blithe's seemingly perfect life masks the scars of a past that's left her cold and immune to emotion. She hides it well, and is content to live behind that mask for the rest of her life.

A zoning change a few weeks before the start of her senior year changes all that when Sophia is forced to attend Gossamer High. It's there she meets Dex Sterling, the boy whose eyes haunt her dreams. He's carefree, handsome, cryptic, infuriating, and he knows more about her than he should. He makes Sophia question the feelings she has whenever she's around him and worse, whenever she's not.

Then one fateful night, Sophia makes a decision that changes everything and, in the darkness that hides nothing, learns the dangerous truth about Gossamer, about Dex, and how he knows so much about her. Now she's left to figure out what it is she wants and whatever her decision, it could end up costing her life.
