Heart of Fire — Maxine Barry

Charis Scott, a princess of the Royal Hawaiian bloodline, isn't prepared for the advent of Jago Marsh into her life, a man who wants to take her company, self-respect, and anything else that he can commandeer. And when she believes this avid collector of Polynesian art has stolen a priceless family heirloom from her, it means war! Meanwhile, eminent vulcanologist Riordan Vane has troubles of his own. He's falling in love with his research assistant and his late wife's brother is out to ruin him. On top of all that, the volcano that he's studying looks set to erupt. Passions are not the only things heating up on the Big Island.
