A single kiss could kill. A single secret could save the kingdom.

Iyla and Marinda have killed many men together: Iyla as the seductress, Marinda as the final, poisonous kiss.

Both girls have felt as though they were living a lie in the past, so moving into the King's palace and pretending to serve him isn't as difficult as it sounds. But when you're a spy, even secrets between friends are dangerous. And each girl has something—or someone—to lose. Does every secret, every lie, bring them closer to the truth or . . . to a trap?
