Brotherhood in Death, J. D. Robb

Edward Mira is a powerful man, with a lot of enemies.  But when the former senator is abducted, Lieutenant Eve Dallas suspects his kidnap is more personal than political.  Someone is seeking justice; the bloodier the better.

The case is personal for Eve and husband Roarke too - Edward's cousin Dennis is a close friend.  But as Eve delves deeper into the case, dark secrets emerge that could tear the family apart.  Edward Mira has friends in very high places - and they seem to be hiding something sinister.  As the investigation takes a shocking turn, Eve finds that not all victims are innocent, and that some bonds are forged not in friendship, but in blood.
