Doctor's Mission (Silhouette Romantic Suspense Series #1534)

Dr. Nick Sandro's top-secret mission: to help undercover agent Cate Olin recover from an attempt on her life. The safehouse? His own apartment, where her body—which he'd dreamed about for years—was suddenly his responsibility. Nick had loved Cate since childhood, but he'd accepted this job as a favor to her family, to her boss. No way he'd cross the line.

For a civilian, Cate's gorgeous doctor sure was secretive. About giving up his career as a surgeon. About not letting Cate in. But when a terrorist hell-bent on revenge came after both of them, saving each other's lives depended on sharing everything.
