First Comes Marriage

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
But she's already found Mr. Right… 

She would rather call her impending nuptials planned than arranged, but she's certain her fiancé is her perfect match. Still, Dr. Meera Malhotra jumps at the opportunity to spend the month before her wedding doing a medical rotation in small-town USA. Getting a taste of independence and improving public health are both part of her plan. Falling for a cowboy? Not so much. Jake Taylor is totally wrong for her, anyway: he raises cattle; she's a vegetarian. He's content with life on the ranch; she's from bustling London and wants to travel. She couldn't possibly throw away everything she's built over something as illogical as love.
