Roxy St. Clair isn’t your run-of-the-mill sweet romance heroine. She’s fierce, feisty, and more likely to throw a punch than bat an eyelash. Callum MacDonald, her rival at Quantico, is a brooding Scotsman—and according to Roxy, excruciatingly insufferable. When the two are unexpectedly paired to crack a diamond smuggling case, sparks fly in all the wrong (and right) directions. Because putting these two together? It’s like mixing fire with fire. Filled with banter, suspense, and slow-burn chemistry, this cozy suspense romance is perfect for fans of NCIS and Clue. Closed-door but sizzling, witty yet heartfelt—Defense & Defend delivers the perfect blend of danger, laughter, and swoon.
