It wasn’t the sun high in the sky that woke her up, nor housekeeping— thanks to Adam, likely, and a Do Not Disturb sign on the door. What got Olive out of bed, even though she really, really didn’t want to face the day, was the frantic buzzing on the nightstand.

She buried her face in the pillow, extended her arm to grope her way to her phone, and then brought it to her ear.

“Yeah?” she bleated, only to find that it wasn’t a call but a very long string of notifications. It included one email from Dr. Aslan congratulating her on her talk and asking for the recording, two texts from Greg (Have u seen the multichannel pipette? Nvm found it.), one from Malcolm (call me when you see this), and . . .

One hundred and forty-three from Anh.

“What the . . . ?” She blinked at the screen, unlocked her phone, and started scrolling up. Could it be one hundred and forty-three reminders to wear sunscreen?

Anh: OOOOOOOOOOOOOOOOOOOOOOOOOOOOOL

Olive groaned, rubbed her face, and decided to skip the other 125

messages and text Anh her room number. She went into the bathroom and reached for her toothbrush, trying not to notice that the spot where Adam’s had been was now empty. Whatever Anh was freaking out about, Olive was likely going to be underwhelmed. Jeremy had Irish step-danced at the department social, or Chase had tied a cherry stem with his tongue. Great entertainment value, for sure, but Olive would survive missing either.

She dried her face, thinking that she was doing a great job of not thinking of how sore she was; of how her body was buzzing, vibrating like it had no intention of stopping, not two, not three, not five hours from now; of the faint, comforting scent of Adam on her skin.

Yeah. A great job.

When she stepped out of the bathroom, someone was about to tear down the door. She opened it to find Anh and Malcolm, who hugged her and started talking so loudly and rapidly, she could barely make out the words— though she did catch the terms “paradigm-shifting,” “life-altering,” and

“watershed moment in history.”

They chattered their way to Olive’s unused bed and sat down. After a few more moments of overlapping babbling, Olive decided to intervene and lifted her hands.

“Hold on.” She was already coming down with a headache. Today was going to be a nightmare, for so many reasons. “What happened?” “The weirdest thing,” Anh said.

“Coolest,” Malcolm interrupted. “She means coolest.”

“Where were you, Ol? You said you were going to join us.”

“Here. I just, um, was tired after my talk, and fell asleep and—”

“Lame, Ol, very lame, but I have no time to berate you for your lameness because I need to catch you up with what happened last night—”

“I should tell her,” Malcolm gave Anh a scathing look. “Since it’s about me.”

“Fair enough,” she conceded with a flourishing gesture.

Malcolm smiled, pleased, and cleared his throat. “Ol, who have I been wanting to have sex with for the past several years?”

“Uh . . .” She scratched her temple. Off the top of her head, she could name about thirty people. “Victoria Beckham?”

“No. Well, yes. But no.”

“David

Beckham?”

“Also yes. But no.”

“The other Spice Girl? The one in the Adidas tracksuit—”

“No. Okay, yes, but don’t focus on celebrities, focus on real life people

—”

“Holden Rodrigues,” Anh blurted out impatiently. “He hooked up with Rodrigues at the department social. Ol, it is with utmost regret that I must inform you that you have been dethroned and are no longer the president of the Hot for Teacher club. Will you retire in shame or accept the treasurer position?”

Olive blinked. Several times. An inordinate amount of times. And then heard herself say, “Wow.”

“Isn’t it the weirdest—”

“Coolest, Anh,” Malcolm interjected. “Coolest.”
