The Millenia Ruby is stolen from the Ritzholdt Museum and insurance investigator Kate Diamond will stop at nothing to retrieve it ... even if it means getting shot at, impersonating an FBI agent and tangling with a live volcano. Enlisting the aid of her retired jewel thief parents and their band of thieves, safecrackers and con men from the Golden Capers retirement village, Kate arms herself with a variety of gadgets and disguises to follow a trail of clues from icy Antarctica to a desolate tropical island. But she soon finds that what started off as an easy job may end with a deadly twist. Why is someone going to so much trouble to keep possession of the ruby? And what, exactly, does Kate's ex-partner, FBI agent Ace Mason, have up his sleeve? Is he really trying to keep her safe as he suggests, or is he simply trying to find the ruby first and take all the credit? By the time Kate realizes things are not as they seem, she may be in too deep. Will she discover the real hidden agenda behind the theft of the gem before it's too late?
