Guest has a reputation that follows him everywhere on campus.

Star athlete. Popular. Confident. The guy who always wins. Tall. Handsome.

When he makes a harmless bet with his teammates—that he can convince the most impossible girl on campus to pretend to date him for one month—it was never supposed to become serious.

That girl is Isabella Laurent.

Nineteen years old, she’s brilliant, sarcastic, and completely uninterested in popularity. She spends more time in the library than at parties, works two jobs to pay for school, and has mastered the art of pushing people away before they get the chance to leave.

When Isabella overhears the bet, she storms into Guest’s life ready to embarrass him.

Instead…

She makes him a deal.

She’ll fake date him—but only because she needs everyone to believe shes taken, so boys would stop flirting with her. In return, Guest gets to save his reputation after word of the bet starts spreading.

What begins as a business arrangement quickly turns into something neither of them expected.

Late-night study sessions become real conversations.

Fake kisses start feeling real.

Jealousy stops being part of the act.

And the line between pretending and falling in love completely disappears.

Three days.

That was how long Isabella Laurent and Guest had been “dating.”

Three days of convincing everyone on campus that the two of them were hopelessly in love.

Surprisingly…

It was working.

boys had stopped trying to corner Isabella after class, believing she’d finally moved on. Guest‘s teammates had quit asking about the bet, convinced he’d somehow pulled off the impossible.

The arrangement was doing exactly what it was supposed to.

The library sat in comfortable silence as Isabella sketched across a sheet of drafting paper, her headphones resting around her neck. Across from her, Guest pretended to read his textbook, though he’d barely turned a page in ten minutes.

Without looking up, Isabella sighed.
