The Highlander's Bride (Highland Trouble #1)
Amanda Forester

After years of fighting in France, Sir Gavin Patrick longs for his Scottish home and for an easier life off the battlefield. However, laden with a shipment of orphans, a massive treasure to transport, and Lady Marie Colette—a sharp-tongued French heiress—Gavin realizes that the real battle is only beginning. Colette expects a painless trip as Gavin transports her to her Highland fiancé, but their relationship takes an unexpected turn…
Forced to pose as a married couple in order to sneak out of France, Gavin and Colette fight against their developing, forbidden attraction…all the while yearning to fulfill their pent-up desire.
