CALL AFTER MIDNIGHT 

Newlywed Sarah Fontaine has just received the news that every wife fears: her husband of two months has died abroad in a hotel fire. Yet convinced he's still alive, Sarah forges an alliance with Nick O'Hara from the U.S. State Department that has the two of them crisscrossing Europe on a desperate search for signs of life. As Sarah and Nick become quarry in the secret world of international espionage, they must risk everything for answers that may prove fatal. 

UNDER THE KNIFE 

For attorney David Ransom, it begins as an open-and-shut case: malpractice. Then Dr. Kate Chesne storms into his office, daring him to seek out the truth—that she's being framed. When another patient turns up dead, David starts to believe her. Somewhere in the Honolulu hospital, a killer walks freely. And now David finds himself asking the same questions Kate is desperate to have answered. 

Who is next—and why?
