A tennis-inspired YA romance, perfect for fans of Challengers, The Summer I Turned Pretty and Carrie Soto is Back.

Billie and her twin brother Tom have been playing tennis together since they were kids. The dream: junior doubles final at Wimbledon. But when Tom falls ill just before their local qualifier, he insists Billie find a new doubles partner and play on.

Enter Harley: her coach's nephew and the neighbour she's hated for as long as she can remember. Harley is everything Billie won't stand for - a lad's lad and friend to Billie's best friend's awful boyfriend - but right now, he's her only option.

The more they play, the worse things get: Billie despises Harley's lack of work ethic, and the more irate Billie gets, the more Harley digs his heels in, determined to teach her how to relax and (literally) take her eye off the ball. And all the while, the doctors can't figure out what's going on with Tom.

Can Billie and Harley make it all the way when seeing eye-to-eye feels impossible? And might there be something more to the tension that grows between them . . .?
