Perfect for you if...
- You love the tension of forced proximity romance with genuine danger woven throughout, not just as a backdrop.
- You're drawn to heroes with a tough exterior but real vulnerability underneath, especially when they doubt their own goodness.
- You want steam and stakes without explicit scenes, and you enjoy series where each book deepens the world around a core security team.
Maybe not for you if...
- You prefer slow-burn romances that take their time; this one accelerates when the threats escalate.
- You're looking for a heroine who's fragile or needs rescuing in a traditional sense; Fiona is accomplished and independent.
- You want literary complexity and moral ambiguity; this is a straightforward good-versus-bad-guy narrative.
