Borrow My Heart by Kasie West

When a girl overhears a guy getting verbally destroyed by his friends for being catfished, she jumps in to save the day—and pretends to be his online crush. A young adult romance from the critically acclaimed author of Places We’ve Never Been.
Wren is used to being called a control freak. She doesn’t care; sticking to the list of rules she created for herself helps her navigate life. But when a cute guy named Asher walks through the door of her neighborhood coffee shop, the rulebook goes out the window.
Asher is cute, charming . . . and being catfished by his online crush. So Wren makes an uncharacteristically impulsive decision—she pretends to be the girl he’s waiting for to save him from embarrassment. Suddenly she’s fake-dating a boy she knows nothing about. And it’s . . . amazing.
It’s not long before Asher has her breaking even more of her own rules. But will he forgive her when he finds out she’s not who she says she is? Wren’s not so sure. . . . After all, rules exist for a reason.
