She hurried to her computer the way she’d hurried to Math Olympiad contests in fifth grade and opened Facebook. She hoped the Brooksides were the type of people who, unlike her, shared their lives often and freely on social media without regard for privacy settings.

She entered Trina Wallace Brookside into the search bar. Only one of the results looked like she could be the right fit. However, Leah opted to rule out the more unlikely candidates first. A few of them were too young. One had been born in England and lived there still.

Finally, anticipation mounting, she brought up the most likely Trina. The woman had created a close-up profile picture from her larger cover photo. The photo captured her solo, standing on a balcony overlooking a beautiful Italian-looking town. She was half turned to the camera with a relaxed smile.

Leah went still. Trina’s face was lined with years, but her facial structure, height, and body type were very similar to Leah’s. She’d styled her blond hair in a long bob that was slightly shorter in back than in the front. She wore a navy-and-white-striped boatneck shirt with roomy sleeves.

Unfortunately for Leah’s purposes, Trina was indeed someone who had regard for privacy settings. She’d made zero information about herself available to people she hadn’t approved as Facebook friends.

Leah typed Sophie Brookside into the search bar. Again, she knew at once, from the picture alone, who her Sophie was. Again, she eliminated the others first before visiting her Sophie’s page.

The circular profile picture of Sophie (Brookside) Robbins revealed a lovely brunette. For her cover photo, she’d chosen an outdoor wedding shot. In it, she was beaming at the camera while holding the hand of her good-looking groom. She’d chosen a strapless wedding dress and knotted her hair into a sophisticated style at the nape of her neck. The veil attached to the top of her bun extended into the breeze in a whimsical line. Her groom regarded her with a besotted grin.

Sophie was slender, stylish, and, judging by this photo, terrifically happy.

Leah had never wanted to marry! Even so, a slither of jealousy snaked around her ribs and squeezed.

Was Sophie (Brookside) Robbins living the life Leah was supposed to have lived?

Was Leah the one who’d been intended for the gown, the veil, the groom? But instead had become, because of all the “nurture” factors in the “nature vs. nurture” equation, the one supporting her brother on a teacher’s salary?

Like her mother, Sophie shared no personal details with those outside her circle of friends.

Leah opened Instagram and hunted for Trina and Sophie there. She only found Sophie, who’d used the same wedding photo on Instagram as on Facebook. Here again, she maintained a private account. Leah tried the remaining social media platforms but wasn’t able to find them.
