Perfect for you if...

  • You love dark romance with genuine danger and moral ambiguity, where the hero isn't simply misunderstood but genuinely conflicted about his orders.
  • You're drawn to enemies-to-lovers plots that flip the power dynamic repeatedly, keeping you guessing about who holds control.
  • You appreciate high-stakes tension that doesn't rely on miscommunication but on characters trapped between loyalty and love.

Maybe not for you if...

  • You prefer romance without cliffhangers or need complete closure within one book.
  • You're uncomfortable with power imbalances, captivity scenarios, or violence played as romantic tension.
  • You want a hero who's unambiguously good from the start rather than one genuinely struggling with orders to harm the heroine.

About this book

The narrator falls in love with Grayson, a dark and dangerous man who makes her feel alive for the first time since her father's death. She then discovers he is an assassin sent to kill her. Now his prisoner, she struggles with conflicting emotions as his touch continues to affect her deeply, even as she fears he may be ordered to harm her. Grayson operates by an absolute code: he eliminates any threat to innocents. Someone is working to convince him the narrator is guilty of something, but of what—and why? As secrets emerge, the narrator learns the shocking truth about why Grayson was sent to silence her. She is left wondering whether the man who gave her a reason to live will become the one who takes it. Crossfire is Book One of the Cross Duet and ends on a cliffhanger. The story concludes in Book Two, Crossover. This book follows Grayson Lockwood, brother of Hunter from the Vendetta Duet. Readers may enjoy starting with Secret Vendetta for additional context.
