Icarus Gallagher is a thief. He steals priceless art and replaces it with his father’s impeccable forgeries. For years, one man—the wealthy Mr. Black—has been their target, revenge for his role in the death of Icarus’s mother. To keep their secret, Icarus adheres to his own strict rules to keep people, and feelings, at bay: Don’t let anyone close. Don’t let anyone touch you. And, above all, don’t get caught. Until one night, he does. Not by Mr. Black, but by his mysterious son, Helios, now living under house arrest in the Black mansion. Instead of turning Icarus in, Helios bargains for something even more dangerous—a friendship that breaks every single one of Icarus’s rules. As reluctance and distrust become closeness and something more, they uncover the bars of the gilded cage that has trapped both of their families for years.
