A soldier heir driven by vengeance, Zarrah clings to two unshakable truths: the Veliant family murdered her mother, and she will stop at nothing until every last one of them falls. As the Endless War between Maridrina and Valcotta ravages on, leaving her people devastated, she seizes command of the contested city of Nerastis, determined to crush the Maridrinian forces once and for all.

But a chance encounter with a mysterious, captivating Maridrinian man ignites a fire within her she never expected. Night after night, their secret meetings blur the lines between enemy and lover, justice and betrayal. As their true identities unfold, Zarrah is torn between her life-long pursuit of revenge and a forbidden passion that could heal a warring empire.

When the drums of war beat louder, Zarrah must make an impossible choice: fulfill her vow of vengeance or risk everything for a love that could bring peace—or destroy them both.
