Tina Wiens is fifteen, coming of age in the rural community of Homer, Ontario. She has been raised in the strict Mennonite tradition hard work, no dancing, no dating, and a strong devotion to the church. It's a restrictive existence that has begun to chafe her, and when her older sister becomes pregnant and is shunned by the church, Tina begins to question the beliefs she has clung to all her young life.

Tina escapes the tension in her home and community when she gets to spend the summer with Tante Tina, her father's aunt, at her farm along the Niagara Escarpment. As she works on the farm, Tina begins to carve out her own sort of independence and understanding of the world she knows is out there. But before she can be truly grown, she must confront a dark secret from her past that could tear her family -- and her community -- apart.
