Molly Ayer has been in foster care since she was eight years old. Most of the time, Molly knows it’s her attitude that’s the problem, but after being shipped from one family to another, she’s had her fair share of adults treating her like an inconvenience. So when Molly’s forced to help an a wealthy elderly woman clean out her attic for community service, Molly is wary.
But from the moment they meet, Molly realizes that Vivian isn’t like any of the adults she’s encountered before. Vivian asks Molly questions about her life and actually listens to the answers.
Soon Molly sees they have more in common than she thought. Vivian was once an orphan, too—an Irish immigrant to New York City who was put on a so-called “orphan train” to the Midwest with hundreds of other children—and she can understand, better than anyone else, the emotional binds that have been making Molly’s life so hard.
Together, they not only clear boxes of past mementos from Vivian’s attic, but forge a path of friendship, forgiveness, and new beginnings.

Born into slavery, Harriet Tubman knew the thirst for freedom. Inspired by rumors of an “underground railroad” that carried slaves to liberation, she dreamed of escaping the nightmarish existence of the Southern plantations and choosing a life of her own making. But after she finally did escape, Tubman made a decision born of profound courage and moral conviction: to go back and help those she’d left behind.
As an activist on the Underground Railroad, a series of safe houses running from South to North and eventually into Canada, Tubman delivered more than three hundred souls to freedom. She became an insidious threat to the Southern establishment—and a symbol of hope to slaves everywhere.

To respect yourself, to love yourself, should not have to be a radical decision. And yet it remains as challenging for an American girl to make today as it was in 1927 on the steps of the Supreme Court. It’s a decision that must be faced when you’re balancing on the tightrope of neurodivergence, finding your way as a second-generation immigrant, or facing down American racism even while loving America. And it’s the only decision when you’ve weighed society’s expectations and found them wanting.
In The Radical Element, twelve of the most talented writers working in young adult literature today tell the stories of girls of all colors and creeds standing up for themselves and their beliefs — whether that means secretly learning Hebrew in early Savannah, using the family magic to pass as white in 1920s Hollywood, or singing in a feminist punk band in 1980s Boston. And they’re asking you to join them.
