Zach is impatient and likes to hurry. Adam likes to take it slow and to tease. But, they'd have worked it all out — if only the end of the world hadn't gotten in the way. Zach Benesh is sure his prediction is right - the island colony of Zahara is about to sink into the ocean. Adam Gray isn't as certain, but he's happy to follow the intense, brilliant geophysicist into the mountains to escape the flooding. Though he'd be even happier without three hundred other people - and their pets - tagging along. He’d like to have Zach all to himself out there. But Zach’s prediction is right and as disaster begins to unfold towards an unstoppable, inevitable conclusion, the two young scientists must become a team in the fight to save their people. They draw strength from their rapidly developing relationship, but the higher Zach and Adam climb, the more difficult the tests they face - as lovers and as men.
