If Elizabeth and Darcy's enemies-to-lovers arc is your favourite part of Pride and Prejudice, this classic Nora Ephron rom-com should be your next stop. Kathleen and Joe are absolute enemies in real life, as she fights to keep her indie bookstore open when his megachain moves into the neighbourhood. What they don't know: they're each other's secret email pen pals. Online, they're falling in love with each other (and out of love with their current real-life partners), but in person, their rivalry grows more and more ruthless. It's also very telling that this '90s rom-com classic is centred on the conflict between megaretailers and indie bookstores — something the literary world is still debating today.
