"Revenge burns hotter than any flame..."

Her sister's murder left ashes in her heart. Now, the Crimson Lily blooms among enemies, and Monte Lucé will feel her thorns.

Lysa Renaud has worn many masks—assassin, thief, avenger. But since her sister Aria's devastating murder, only one identity matters: The Crimson Lily, a name whispered with fear in the shadows.

With the dangerous and enigmatic Rian Al'Deur as her reluctant ally, Lysa crosses the Endless Sea to Monte Lucé—a glittering paradise of wealth and excess where deadly secrets lurk beneath every smile. Her target: Saito, the man who stole Aria's life and possesses weapon blueprints that could ignite war across continents.

But Monte Lucé bows to no one except the mysterious Collector, whose invisible web of spies and assassins makes him the city's true master. When Lysa and Rian form an uneasy alliance with the seductive Evee della Sarcova, they're drawn into a deadly game where loyalty shifts like sand.

By day, they navigate the dazzling Festival of Lights and elite casinos. By night, they plot heists that will bring them closer to Saito. Yet with each step deeper into the Collector's domain, the line between hunter and prey blurs.

As desire and vengeance intertwine, Lysa faces an impossible choice. Trust her heart—which inexplicably pulls her toward Rian—or trust her instincts, which warn that in Monte Lucé, even a lover's embrace can conceal a blade.

The Crimson Lily came to deliver justice, but in a city built on beautiful lies, will her quest for retribution cost her the one thing she never expected to find again?

Love.
