16-year-old Ash is counting down the days until she and her mother move away from their prairie hometown of Treade. It's Ash's summer of goodbyes until, after a turn of fate, she finds her way into the mysterious, condemned building on the outskirts of town. What she finds inside - or what finds her - is an untouched library, inhabited by an enchanting mute named Li. Brightened by Li's charm and his indulgence in her dreams, Ash becomes locked in a world of dusty books and dying memories, with Li becoming the attachment to Treade she never wanted.
