Winning means power over the ancient world's richest trade route. Losing means an empire erased from history.

At the mouth of the Tamraparni river sits Korkai, a maritime capital whose pearls once adorned Roman emperors and Egyptian queens, guarded by a war machine no foreign power has broken. Alexandria wants it broken. Thea is the operative they trained to do it, sent to deliver its pearl fortune into foreign hands.

Prince Aadhiran has spent his life building Korkai's defenses and answers to no crown but his own. He does not expect a spy in his court. He does not expect to need one, either, when assassins strike in temple shadows and his father's court starts bleeding traitors from the inside. As Thea's mission collides with a conspiracy larger than either empire, she has to choose between the masters who made her and the kingdom that is starting to feel like home.

Two deadly adversaries, one crown, and a war that will be won with secrets long before it is won with steel.
