Note: This is the original Adult (fantasy/romance) version. Fantastic Beasts meets Assassin's Creed in this epic, gripping fantasy romance from debut author Maxym M. Martineau. Exiled beast charmer Leena Edenfrell is in deep trouble. Empty pockets forced her to sell her beloved magical beasts on the black market—an offense punishable by death—and now there's a price on her head. With the realm's most talented murderer-for-hire nipping at her heels, Leena makes him an offer he can't refuse: powerful mythical creatures in exchange for her life. If only it were that simple. Unbeknownst to Leena, the undying ones are bound by magic to complete their contracts, and Noc cannot risk his brotherhood of assassins...not even to save the woman he can no longer live without.

Noc Feyreigner, leader of the assassins of Cruor, is living on borrowed time. If he fails to kill his final mark―Leena Edenfrell―his own life will be forfeit. With the dark magic of Curor's Oath testing his control, Noc has to fight with everything he is to keep the woman he loves safe. Leena would do anything to help Noc overcome the oath. So when she hears of a beast rumored to have the power needed to save Noc's life, she is quick to embark on an expedition to the frozen north. But what starts as a hunt for a magical beast quickly turns into Leena and her trusted band of assassins as prey...and time is running out.

Serpent & Dove meets A Curse So Dark and Lonely in this vividly arresting addition to the The Beast Charmer series! Leena Edenfrell never dreamed of igniting a war, and her pair bond, Noc Feyreigner, never wanted to set foot on a battlefield again. But when their enemies combine forces, they have no choice but to fight. While Noc makes moves to reclaim his throne, Leena acts as the new Crown of the Charmer's Council, searching for a way to stop the enemy from raising an ancient dragon destined to burn their world to ash. But no matter how hard Noc and Leena fight, the odds are stacked against them, and soon a winged shadow reigns over Lendria. It's then they learn the true price of victory: in order to tame the terrifying beast, Leena will have to sacrifice her own heart...and perhaps lose herself in the process.
