Even in the 24th century, three is definitely a crowd. Imzadi: to the people of the planet Betazed, including Counselor Deanna Troi of the Starship Enterprise, it means "beloved" and denotes a special closeness that can never be truly broken. Or can it? Now David examines the heart of Deanna Troi from an altogether different perspective, as he reveals for the first time the full story of Troi's troubled romance with Lieutenant Commander Worf. Soon mutual respect leads to much stronger emotions as they embark on an unexpected courtship, much to the surprise and discomfort of William Riker.
