Book 1

Distant Echoes

by Colleen Coble

Published 31 July 2006

It feels like paradise, but deadly secrets lie beneath the waves off the coast of Kauai.

Sometimes Kaia Oana thinks her dolphins are more humane than humans. As a mammal intelligence researcher, Kaia has learned a thing or two about the goodness and intelligence of dolphins-and as a natural scientist in close proximity to weapons developers, she's learned a thing or two about humans as well.

When a tourist catamaran explodes off the coast of the Hawaiian island of Kauai, Kaia and her trained dolphin, Nani, rush to aid the search and rescue effort. After hours of searching, an exhausted Kaia is pulled from the water by Lieutenant Commander Jesse Matthews of the U.S. Navy.

Lieutenant Matthews is accustomed to following protocol-and a civilian-dolphin rescue is not typical operating procedure. But when his colleagues ignore the possibility that missile research had something to do with the sunken catamaran, Jesse recruits Kaia and her dolphin to help him conduct his own investigation. The olive-skinned mermaid had impressed him-in more ways than one.

As their rogue investigation takes them into the waters surrounding the sunken boat-and their personal chemistry takes them into other uncharted territory-Kaia and Jesse discover that they have become targets themselves. Someone doesn't want them snooping around that wreckage . . . someone desperate enough to kill.

Kaia and Lieutenant Commander Jesse Matthews team up in the investigation - but as they edge closer to the truth about the incident, their own lives are threatened.

Black Sands

by Colleen Coble

Published 10 November 2005

Page-turning romantic suspense set amid the gorgeous beauty of Hawaii and the impending danger of a volcano.

A brainy-and perpetually single-volcanologist, Annie Tagama works alongside her father at Hawaii Volcanoes National Park. But despite her pedigree, Annie has lost her passion or volcanology. She's quietly grieving the mysterious loss of her brother in the Middle East.

When Annie discovers that her brother might still be alive-and in trouble-she shakes off her malaise and joins forces with Mano Oana, the unnervingly handsome family friend she had always blamed for her brother's death.

As Annie and Mano investigate-and find that they have a lot more in common than tragedy-an evil force gathers strength on the main island. An ancient cult has reemerged-and Annie's little sister is somehow involved. As the old religion bubbles to the surface like lava, the old practices are not far behind . . . including human sacrifice.

Annie and Mano are desperate to find her brother and save her family from destruction before the ancient evil smothers them all in an earth-shattering eruption.

This full-length romantic suspense can be read as a standalone, but is also part of the Aloha Reef Series.
