The Fiat Girls™ books are an unqualified delight—faithful, engaging, rich in humanity, and beautifully written. Claire Swinarski has done a masterful job of making the saints come alive for young readers, and I am so grateful that my daughter will get to grow in friendship with Therese, Teresa, Rose, and other amazing women through these books. They are a gift to moms and daughters alike!

— Emily Stimpson Chapman

When my daughters ask me questions about Saints, they usually want to know, "Were they in jail?" or "How did they die?" I can't wait to hand my daughters Fiat Girls™ and see the books spark a new question: "Could this Saint be my friend?"

Fiat Girls™ brings saint stories to life in a whole new way, welcoming readers into the real world in which a real person lived. Claire helps us learn about a saint's holiness not just through dates, facts, figures, or even pictures, but through a beautiful, engaging, well-written story that will connect with a child's heart and open their mind.

I loved Fiat Girls™ and cannot wait to give these to my own daughters and dive into the great treasure of saint stories that will inspire holiness in their hearts and help them grow in friendship with the saints in heaven. Just as I claim my American Girl Doll books as an inheritance, I know that Fiat Girls™ will be cherished by my daughters for years to come.
