When six-year-old Abel Cohen wanders off from her parents' cabin in the woods of Maine, she is rescued by Zac Lipton, a girl barely older than herself, who knows her way through the trees because they are where she has spent her entire life. That meeting sparks a summer-long friendship filled with laughter, stories, adventures and, of course, spinning.

Fourteen years later they meet again, and after a rocky introduction, strengthen that bond of friendship formed so many years ago. Abel loves introducing Zac to the world she's barely glimpsed from her overlook in the woods, and Zac, in turn, shares her love of the outdoors. Together they explore not just their surroundings, but their fears, hopes and feelings.

When Abel nears the end of college and her regular trips to the cabin, will she be able to convince Zac to leave her beloved woods and join her in the bustling city of Boston? Or will Zac decide to remain in her comfort zone, hidden behind the branches and tree trunks, safe from the chaos of civilization?
