An insect landed on her shoulder and began to walk down her back. As Laurel swatted at it her fingers touched something. She stretched her arm back a little farther and felt for it again. It was still there; a round bump, just barely big enough to feel under her skin. She craned her neck but couldn’t see anything past her shoulder. She touched it again, trying to figure out what it was. Finally she stood, frustrated, and headed back to the house in search of a mirror.

After locking the bathroom door, Laurel sat on the vanity, twisting until she could see her back in the mirror. She pulled the top of her sundress down and searched for the bump. She finally spotted it right between her shoulder blades—a tiny, raised circle that blended in with the skin around it. It was barely noticeable but definitely there. She poked it tentatively—it didn’t hurt, but poking it did provoke a sort of tingling feeling. It looked like a zit. That’s comforting, Laurel thought wryly. In a completely non-comforting way.

Laurel heard her mother’s soft steps creak down the hall and poked her head out the bathroom door. “Mom?”

“Kitchen,” her mom called with a yawn.

Laurel followed her voice. “I have a bump on my back. Could you look at it?”

she asked, turning around.

Her mom pushed on it softly a few times. “Just a zit,” she concluded.

“That’s what I figured,” Laurel said, letting the top of her dress snap back up.

“You don’t really get zits.” She hesitated. “Have you started…you know?”

Laurel shook her head quickly. “Just a fluke.” Her voice was flat and her smile was sharp. “All part of puberty, like you always say.” She turned and fled before her mother could ask any more questions.

Back in her room she sat on her bed, fingering the small bump. It made her feel strangely normal to get her first zit; like a rite of passage. She hadn’t experienced puberty quite like the textbooks described it. She never got zits and, although her chest and hips had developed the way they were supposed to—a little early, actually—at fifteen and a half she still hadn’t started her period.

Her mom always shrugged it off, saying that because they had no idea what her biological mother’s medical history was, they couldn’t be certain it wasn’t a perfectly normal family trait. But she could tell that her mom was starting to get worried.

Laurel dressed in her usual tank top and jeans and started to pull her hair into a ponytail. Then she thought of the irritated blemishes she occasionally saw dotting other girls’ backs in the locker room and left her hair down. Just in case the bump developed into something ugly later on.

Especially at David’s house. That would suck.

Laurel grabbed an apple as she walked out the door and called good-bye to her mom. She was almost to David’s house when she looked up and saw Chelsea jogging the other way. Laurel waved and called to her.

“Hey!” Chelsea said, smiling as her curls blew lightly around her face.

“Hi,” Laurel said with a smile. “I didn’t know you were a runner.”

“Cross-country. Usually I practice with the team, but on Saturdays we’re on our own. What are you doing?”

“I’m headed to David’s,” Laurel said. “We’re going to study.”

Chelsea laughed. “Well, welcome to the David Lawson fan club. I’m already president, but you can be treasurer.”

“It’s not like that,” Laurel said, not completely sure she was telling the truth.

“We’re just going to study. I have a bio test on Monday that I’m totally going to blow without some serious intervention.”

“He’s just around the corner. I’ll walk you there.”

They rounded the corner and heard the mower. David didn’t see them as they walked up and they both stood there, watching.

He was pushing a lawn mower through the thick grass, wearing only a pair of jeans and old tennis shoes. His chest and arms were long and wiry but corded with lean muscle—his skin was tanned from the sun and glistened with a light sheen of sweat as he moved almost gracefully in the gentle morning sunlight.

Laurel couldn’t help but stare.

She’d seen guys running around without shirts countless times, but somehow this was different. She watched his arms flex as he reached a particularly thick patch of grass and had to force the mower to keep going. Her chest felt a little tight.

“I think I’ve died and gone to heaven,” Chelsea said, not bothering to hide the appreciation in her eyes.

As if feeling them watching, David suddenly looked up and met Laurel’s eyes.

She dropped her chin and studied her feet.

Chelsea didn’t even blink.

By the time Laurel looked up again, David was pulling on a shirt. “Hey, guys.

You’re up early.”

“Is it early still?” Laurel asked. It was almost nine o’clock, after all. “Oh,” she said, embarrassed, “I forgot to call.”

David shrugged with a grin. “That’s okay.” He gestured at the lawn mower. “I’m up.”

“Well, I gotta run,” Chelsea said, her breathlessness back rather suddenly.

“Literally.” She turned so only Laurel could see her face and mouthed, “Wow!”

before waving at them both and sprinting down the street.

David chuckled and shook his head as he watched her go. Then he turned to Laurel and pointed toward his house. “Shall we? Biology waits for no man.”
