The Montclair Emeralds and Fulfillment

The tragic love affair between Diandra Casey's mother and Greg York's father had left them both a legacy of bitterness--a legacy old Bartholomew York couldn't accept.  Knowing these two were meant to be united, he wasn't beyond using manipulation  --  and a magical talisman to make it happen....

Thus Diandra and Greg found themselves sharing duty in Bart's town house, cataloging his treasures. But such intimacy aroused only their hostility... until they came across a strangely powerful necklace. Suddenly, the atmosphere between them changed. Suddenly, their closeness seemed the fulfillment of destiny.
