Every woman needs a hobby. Roya’s is murder. After a childhood in a gilded cage, Roya has devoted her life to learning about poisons and weapons from her sexy and much older mentor, Thorn, the most famous and deadly assassin in the Guild. But when he flunks her out of the Assassins Guild, Roya has the urge to use her murdering skills on him. Instead, she runs away, and straight into danger. Now she’s being hunted by cruel kings and powerful warlords, somehow all privy to her deepest secret—that she is a mythical Omega, thought to be extinct. When Thorn joins forces with a prince, a warrior-scholar, and a pirate to protect her, Roya feels trapped again. She’s dead set on killing the desire she feels for the men who may be her soulmates. But there may not be enough poison in the world to save her from her true enemy. What comes after the bloody, happy ending? A happier, bloodier one. Roya’s story ends with a new novella, The Assassin’s Gift. Roya is the third volume in The Lost Lines Collection, a series of interconnected RH fantasy Omegaverse romances with humor, angst, and plenty of spice. This omnibus edition contains the full-length novel, The Assassin’s Promise, and the new epilogue novella, The Assassin’s Gift, as well as maps and new character art. For mature readers only.
