Wren was bought at seven and trained for a single contract. At nineteen she finally reaches him — and fails, because the prince greets her by the name she was born with. A name nobody has spoken since she was sold. Bound by a court debt she cannot refuse, she stays in his household as his sworn blade, each of them using the other with perfect clarity about why. But the Thorn Court's debts are being called in, and Wren is about to learn her contract was never about the prince at all.
