Katie McCabe doesn't believe in fate - she believes in training, hard work, and not letting anyone get close enough to break you. But when she forgets her cousin's birthday, a last-minute dash into a flower shop changes everything. Nell Carter has seen all kinds of customers, but none quite like the Irish whirlwind who crashes through her door demanding "something that says 'I didn't forget your birthday, I just have commitment issues.'" It's meant to be a one-off. But Katie keeps coming back. At first for flowers. Then for the calm. Then for Nell. And Nell? She knows better than to fall for someone whose entire life is lived in the spotlight. But Katie - chaotic, fierce, unexpectedly kind - is like sun on soil Nell didn't know needed tending.
