Black Sands (Aloha Reef Series #2)

Colleen Coble

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.
