Private investigator Julianne McCarren would give anything to have her husband alive again but settles for the occasional comment he makes in her head. His wedding gift to her, a blue diamond necklace named Angel Falls, goes missing from her safety deposit box in New York, with only a replica in its place. Aided by Security Specialist Macklin Pierce and her niece, Julianne sorts through obsessed in-laws, a grieving bank vault escort, a scheming mistress, and a threatening gang member, all with Russian ties. Who made the replica, why was a bicycle messenger killed, and will Julianne recover her necklace before it's lost forever?
