What Seemed Like Paradise Suddenly Becomes a Fiery Nightmare.

As the Petrel sails closer toward the House of the Sun, Cheney Duvall and Dr. Walker Baird, her colleague from St. Francis Hospital in San Francisco, arrive in Hawaii to try to convince Shiloh Irons to return with them. Though Shiloh believes the Winslows might be his long-lost family, Cheney has discovered some disturbing facts about Bain Winslow and has traveled all this way to warn Shiloh. The Winslows have refused to acknowledge any kinship to him and believe he is nothing more than a con man bent on stealing the family fortunes.

When Cheney pays a call on the Winslows with Dr. Baird to thank them for a generous donation to the hospital where she works, her curiosity and ire are raised by Denise Winslow's haughty demeanor. She and Walker set out to help Shiloh unravel the mysteries that seemingly surround the Winslows' determination to drive him from the island. With the fish compass and tapestry stolen the only tangible clues to Shiloh's origins will he ever learn his true identity?

Caught between the river of lava creeping toward the beach and the waters teeming with frenzied sharks and poisonous Portuguese man-of-war, Cheney must make the most difficult decision of her life. Will Shiloh return in time to rescue them from the fiery destruction spewing from Haleakala?
