Two enemies, one goal: steal each other’s hearts. Scarlett Grey, disgraced assassin, is determined to get revenge. Quinn Adams, medic turned-poisoner for hire, is her deadliest rival. For years, they’ve stolen each other’s clients, sabotaged each other’s business, and occasionally… slept together. When the Magician Queen offers an irresistible deal, Scarlett and Quinn are forced to work together.
