In Search of Truth by Sharon Wray

Buried treasure… buried feelings…all about to surface…
Anthropologist Allison Pinckney is stunned when she inherits the key to a seventeenth century pirate cipher that makes her the target of two brutal arms dealers. Now, to save those she loves, she must solve the cipher. With this perilous mission growing ever more dangerous, she reluctantly seeks help from ex-Green Beret Zack Tremaine, the one man she’s been avoiding. Because if she gives into her long-buried feelings for him, it could cost them their lives.

Zack Tremaine is haunted by regrets. Years ago, he betrayed his men and lost the only woman he ever loved. Now that his men are caught in a fierce rivalry between two deadly enemies, his only hope is to team up with Allison. She holds the secret to a pirate treasure, and he must take the chance to save his men and redeem his honor. Even if she breaks his heart…again.
