Series numeration from Fantastic Fiction.

Annie Tagama has always been content to bask in the glow of her more flamboyant brother and sister and to quietly assist her father in his volcano research. Annie does, however, have 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, more beautiful sister goes missing, she's forced to turn to her former love-now her sworn enemy-for help. Mano Ohana believed he had made a fateful mistake that cold night-a mistake that had 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 nothing is what it seems: 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
