The Stone Lantern by Samantha Stevens

Two men searching for an ancient burial ground on the Big Island of Hawaii finally find it, but they also find something that they were not expecting. In the same tomb with the remains of a thousand year old Hawaiian chief, they find the skeleton of a 20th century murder victim with its skull bashed in. Jessie Bradford’s father has been missing for 36 years and she is sure the skeleton is his, but who would want to murder her father? Detective John “Mac” McIntire investigates, but Jessie does some investigating of her own.
