Menehune in Kauai: Peyton Brooks, FBI, Book 7 (Unabridged‪)‬

When Peyton and Marco embark upon a vacation to Kauai, they are only looking for sunshine, blue waters, and white sand. Although they feel guilty about stealing time for themselves, they know they may not get another chance to concentrate on each other without the pressure from both of their jobs driving them apart.

The beautiful island of Kauai welcomes them, and they begin to relax, until a body is found floating in the hot tub at their hotel with a poisoned arrow sticking out of his chest. Whether they want it or not, they are suddenly thrust into a mystical whodunit, but the one thing Marco and Peyton do well is work together, and there is no one who can solve a case quite like they can.
