Desperate Escape by Lisa Harris

When Dr. Maddie Gilbert is kidnapped by rebel forces in West Africa, special ops agent Grant Reese races to rescue her. But the ruthless drug traffickers holding Maddie hostage have powerful connections–maybe even inside the US government. And they'll go to any lengths to silence her–permanently. Grant knows that getting Maddie free and safe is just the first step of this mission. Because he's fallen for the spirited beauty, and as her enemies pursue them, Grant must face a second battle–the one to win her heart.
