Black Sands, Aloha Reef Series #2

As a volcano on Hawaii begins to rumble, sudden, inexplicable tragedies bring an unlikely couple together.
Annie Tagama has always been content to bask in the glow of her brother and sister and to quietly assist her father in his volcano research. Annie has a secret crush on Mano Ohana, though he's never noticed her. Her devotion turns to disdain after a mistake by Mano kills her beloved brother.
But when her younger sister goes missing, she's forced to turn to her former love, now her sworn enemy, for help.
Mano Ohana made a fateful mistake that cold night. A mistake that probably cost the life of his best friend, Tomi Tagama. But the night before he is to bring Tomi's belongings to his family, Mano discovers his friend is still alive--but he's in serious danger. Worse, the danger threatens to spill over to the rest of the Tagama family-and the entire Hawaiian islands.
