From award-winning author Pablo Cartaya comes a deeply moving middle grade novel about a daughter and father finding their way back to each other in the face of their changing family and community. A SCHNEIDER FAMILY BOOK AWARD HONOR FOR MIDDLE GRADE Emilia Torres has a wandering mind. It's hard for her to follow along at school, and sometimes she forgets to do what her mom or abuela asks. But she remembers what matters: a time when her family was whole and home made sense. When Dad returns from deployment, Emilia expects that her life will get back to normal. Instead, it unravels. Dad shuts himself in the back stall of their family's auto shop to work on an old car. Emilia peeks in on him daily, mesmerized by his welder. One day, Dad calls Emilia over. Then, he teaches her how to weld. And over time, flickers of her old dad reappear. But as Emilia finds a way to repair the relationship with her father at home, her community ruptures with some of her classmates, like her best friend, Gus, at the center of the conflict. Each Tiny Spark by Pablo Cartaya is a tender story about asking big questions and being brave enough to reckon with the answers.

Perfect for readers of Song for a Whale and Counting by 7s, a neurodivergent girl campaigns for a memorial when she learns that her small Scottish town used to burn witches simply because they were different. "A must-read for students and adults alike." -School Library Journal, Starred Review Ever since Ms. Murphy told us about the witch trials that happened centuries ago right here in Juniper, I can’t stop thinking about them. Those people weren’t magic. They were like me. Different like me. I’m autistic. I see things that others do not. I hear sounds that they can ignore. And sometimes I feel things all at once. I think about the witches, with no one to speak for them. Not everyone in our small town understands. But if I keep trying, maybe someone will. I won’t let the witches be forgotten. Because there is more to their story. Just like there is more to mine. Award-winning and neurodivergent author Elle McNicoll delivers an insightful and stirring debut about the European witch trials and a girl who refuses to relent in the fight for what she knows is right.
