One quiet night in Boulder, Colorado, Aspen Yellow-Sunrise Taylor made a mistake.

In the next instant, her life changed forever.

Aspen doesn’t want to remember the devastating car accident that killed Katelyn Ryan, a sleek-haired popular soccer player. But forgetting is hard– because Katelyn may have died — but she didn’t leave. Her ghost is following Aspen around, and heading into senior year, it’s kind of a problem. Especially when Katelyn’s gorgeous former boyfriend Ben appears to be the only person at school with a clue as to how Aspen feels.

Popularity, college, Homecoming Court, hot guys – none of these things ever mattered to Aspen. She’s been busy trying to rein in her giant mass of blonde curls, keep her stoner mother Ninny away from Toaster, her mom’s awful bongo drumming boyfriend, and prevent her best friends Kim and Cass from killing – or kissing – one another. But with Ben sitting next to her in Physics looking all too gorgeous, Katelyn’s spirit dogging her steps, and her obsessive snow-globe collecting therapist begging her to remember all the things she wants to forget, Aspen is thrust into a vivid, challenging world she can’t control … and doesn’t want to.

A darkly funny, emotionally gripping story of opening up, letting go, and moving on, ASPEN is about the best-worst accident of your life … and what comes next.
