The Meet Queue-t by Ellie Harrow

Twelve hours. One fake relationship. What could possibly go right?

Tessa Nelson is done with love. After her ex-fiancé cheated and her mum died, the only thing she’s looking for is closure. That’s why she’s waiting in the longest line of her life to pay her respects to the Queen’s coffin. It’s what her mum would’ve wanted.
She didn’t expect to find Oliver Murphy: a warm, quietly funny history professor who makes her feel seen. When her ex appears out of nowhere (seriously, what are the chances?), Oliver doesn’t hesitate to play along after she blurts out he’s her boyfriend.
Fake dating never felt so real.
But the Queue must come to an end, and so will they—unless she’s prepared to risk the one thing she’s been protecting.
Her heart.
