Triangle - Peter David

'Imzadi' is a powerful Betazoid term that describes the enduring bond between lovers, and Triangle: Imazadi II is the untold story behind the tragic love that united two of the Enterprise crew: ship's counsellor Deanna Troi and the Klingon Commander Worf. At first glance they could not be more different. She is a calm and gentle empath, acutely sensitive to the needs and emotions of others. He is a fierce Klingon warrior, dedicated to a harsh and warlike code of honour. Brought together by their mutual care for Worf's son Alexander, they embark on an unexpected courtship, much to the surprise and discomfort of Deanna's former lover, Commander William Riker.
But does Worf's future truly lie with Deanna ... or on a distant outpost called Deep Space Nine? And who will Deanna ultimately choose to call 'Imazadi'?
