Eyes of Fire by Heather Graham

Get swept away by this classic romantic suspense by the queen of the genre, New York Times bestselling author Heather Graham, where a treasure in the ocean is worth killing for.

Having already lost two men in her life to the lure of the bounty beneath the sea, Samantha Carlyle wants nothing to do with treasure hunts. She wants to be left in peace to run her dive resort on Seafire Isle.
But unexplained events continue to happen. Adam O’Connor—Samantha’s ex-lover—arrives unannounced on the tiny island. Samantha becomes the target of an attempted kidnapping. And she’s beginning to realize that none of the resort’s guests are who they claim to be.

Caught in an undertow of lies and murder, Samantha confronts the secrets that have, for centuries, been drawing men to their watery graves. And she realizes that the little she knows about the lost treasure is more than enough to get her killed.
