Query: Love is the greatest challenge.

Eugenides, the Queen's Thief, is not just a thief, he's a spy, and he's been spying on the queen of the neighboring kingdom of Attolia since they were both children. He fell in love with her the first time he saw her, but she's become cruel and ruthless under the strain of ruling her realm, and when she catches him in her palace, spying, she turns all her cruelty on him in a way that nearly breaks both of them.Despite her unforvigable act, Eugenides can't help but understand the pressures on this queen, can't help understanding her, and despite his fear and fury, can't help loving her.
