  • Beautiful Bastard
  • Crossfire Series (Sylvia Day)
  • Protective Instinct (Suzanne Wright)

Perfect for you if...

  • You enjoy romantic suspense where the chemistry between leads feels earned rather than instant, with both characters bringing real baggage to their connection.
  • You want action sequences that drive the plot forward rather than interrupt it, set against high-stakes scenarios like international crime and corporate conspiracy.
  • You appreciate protagonists who are competent and resourceful in crisis, especially a heroine who doesn't need saving so much as she needs a partner to survive with.

Maybe not for you if...

  • You prefer slow-burn romance where emotional intimacy develops gradually before physical attraction takes centre stage.
  • You're looking for literary complexity in your suspense. This is plot-driven entertainment, not psychological depth.
  • You want your action grounded in realism. High-octane scenarios and convenient reveals won't feel plausible to you.

About this book

April Livingston is a bestselling author living in New York City whose personal life is marked by an unstable on-again, off-again relationship. Seeking an escape, she attends a high-profile fundraiser on a luxury yacht, where she witnesses a murder. She flees and becomes a target of a Russian arms dealer intent on eliminating witnesses. Ace, a former Delta Force operator now working in private security, is assigned to protect April. Taciturn and detached, he typically takes assignments abroad to avoid personal entanglement. His attraction to April is immediate and intense, complicating his usual approach to work and relationships. As they evade those pursuing her, April discovers secrets from her past that force her to confront difficult truths. With danger mounting and their bond deepening, Ace commits to protecting her at any cost. The story combines action, romance, and plot twists as two guarded people navigate survival and connection.
