Saving Savannah by Kathy Ivan

Recovering from a horrific ordeal that nearly ended her life, Savannah Sloane feels she’s finally moving forward with her life. But when reminders of the nightmare she survived begin arriving, her worst fears come crashing back, and the only person she trusts to help her is Stefan Carlisle.
Haunted by memories of the woman he helped rescued, computer expert Stefan Carlisle drops everything when Savannah calls. Rushing to San Diego, he’s intent on eliminating any threat to the woman he’s been unable to forget.
To win a twisted game of cat and mouse, Stefan must use every computer skill he possesses, along with Savannah’s Navy SEAL friends, to mount a rescue. He’ll do whatever it takes to keep her out of the hands of a madman. But will it be enough to save Savannah, or will she be lost forever to a madman bent on revenge?
