A surprise mind-meld!

Lillith, a middle-aged, snow-white, winged mare surprisingly melds for life with the newborn Supreme Don heir, helping to raise him through the tribulations of reaching adulthood.  Then, he refuses his hereditary position on the death of his father, leaving his people rudderless in a time of threat to both species.

Re Lillith: "This is a wonderful introduction to a fantasy world of winged horses, telepathic communication, and inter-species relationship that keeps you on your toes and anxious for more."  Richard E
