The Operation: Midnight series by Linda Castillo is a five-book romantic suspense line published through Harlequin Intrigue between 2005 and 2007. Each book pairs a strong female lead with a male protector in a high-stakes situation involving covert operations and danger.
Castillo wrote these books before she became widely known for her Kate Burkholder mystery series. The Harlequin Intrigue format gave her room to combine action plots with romance, and the Operation: Midnight books follow that formula closely. The titles suggest the covert, after-dark nature of the missions that drive each story.
For fans of Castillo’s later work, these earlier books show where she developed her skills in building suspense and writing tense, fast-paced scenes. The romantic suspense format is different from her police procedural mysteries, but the tight plotting carries through both.
