Photographer and sometime agent Nova Blair must work with ex-lover Joe Cardone -- the man she loved and left -- to save hostages in South America. In the process, Nova learns that working with Joe, and committing to him, may be something she can do after all. Captive Dove (3), by Judith Leon, is exciting and fast-paced. But the story could use more color in places. It focuses too much on dialogue and could use more description.
