For sixteen-year-old Charlotte Reynolds, aka Charlie, being raised by a single dad and three older brothers has its perks. She can outrun, outscore, and outwit every boy she knows—including her longtime neighbor and honorary fourth brother, Braden. But when it comes to being a girl, Charlie doesn't know the first thing about anything. So when she starts working at chichi boutique to pay off a speeding ticket, she finds herself in a strange new world of makeup, lacy skirts, and BeDazzlers. Even stranger, she's spending time with a boy who has never seen her tear it up in a pickup game.

To cope with the stress of faking her way through this new reality, Charlie seeks late-night refuge in her backyard, talking out her problems with Braden by the fence that separates them. But their Fence Chats can't solve Charlie's biggest problem: she's falling for Braden. Hard. She knows what it means to go for the win, but if spilling her secret means losing him for good, the stakes just got too high.
