SHARPSHOOTER (4) by Cynthia Eden: Two years ago, Gunner Ortez saved Sydney Sloan’s life on a mission gone wrong, but he also lost his brother, Slade, whom Sydney was going to marry. Since then, he’s watched her back in every mission and hidden the fact that he’s always been in love with her. But after a passionate night together, Gunner and Sydney must go back to the jungle on a hostage rescue mission — for the man they thought dead. As the danger escalates and evidence points to Gunner possibly being a double agent, Sydney knows he’s her only hope of surviving the attacks that seem to arise on every front. Eden’s Shadow Agents series just keeps getting better, as her characterizations become more complex and the premises more thrilling.
