The Flame — Jean Johnson

Eight brothers, born in four sets of twins, two years apart to the day -- they fulfill the Curse of Eight Prophecy. Though no longer trapped in exile, their growing family faces new problems. Now that its his turn to look for a bride, the seventh-born brother burns with curiosity and anticipation...

Koranen of Nightfall is tired of the Curse -- in his case, a destructive flame that courses beneath his flesh. His brothers have wives and lovers, but all Koranen has are blistering reminders of a touch that burns...unless he can find a woman able to endure the literal heat of his passion. Then the Aquamancers arrive, at last affording Koranen the chance to find his Destined bride.

Ostracized for being too good at her job, Danau is resigned to her punishment: never knowing love. But fire and water always create steam, and things do get steamy as Danau and Koranen gradually realize they were meant for each other -- even as Nightfall's future becomes flooded with more trouble than either of them could have imagined.
