Fever

The pantheon of gods were displeased when Kane, one of their major gods, fell out with his lover Kanaloa, one of the ruling forces over the Hawaiian Islands. Condemned to an eternal earth-bound life as a shape-shifting vampire, Malakai has one chance to break the curse. He must never fall in love and he must never intervene in human problems.

All that goes astray when he meets Jepoi, a young male nurse working on the Big Island of Hawaii. Malakai falls for Jepoi and can't resist him, but then all hell literally breaks loose when Malakai saves Jepoi from ancient and deadly disease that returns to the fatal shores of Hawaii.
