Mistaken Target

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
MIDNIGHT INTRUDER 

The isolated island retreat was the last place anyone would look for former socialite Samantha James. Yet danger finds her anyway—accidentally. The assassin who breaks into her room doesn't realize that she and Diego Cruz—his real target—switched cabins. But it doesn't matter that she's not who he came to attack. She's seen his face…so she's his new target. Blaming himself for her situation, Diego will do anything to keep Samantha safe. After years working undercover as an FBI informant, he's accustomed to danger. But he's not used to having a beautiful woman's life resting in his hands…or a killer with everything to lose closing in on his heels.
