Our story
Born from a missionary family's kitchen table
Wonder Letters grew out of a simple question: how do you help your own children care about people they've never met, in places they've never been?
Meet Hannah
Hannah Hagarty is a mother of ten, a published author, and a former overseas missionary. She and her husband worked in Tbilisi, Georgia, where very few people had ever heard the gospel. It was hard, beautiful work, and it marked their whole family.
When God, in His sovereignty, brought them home through a tragic set of circumstances, Hannah noticed something. Her kids remembered the people. They remembered the smell of chai brewed over a charcoal stove, the sound of the call to prayer echoing across rooftops, the taste of flatbread shared with new friends. Those memories shaped their hearts.
But most American kids never get those moments. They hear about "the nations" in Sunday school, maybe see a map on the wall. It's abstract. Distant.
Hannah wanted to change that. She picked up her paintbrushes, sat at the kitchen table, and started illustrating.
The first Wonder Letter arrived in mailboxes in January 2025. It was handwritten, hand-illustrated, and told the story of a child's life in an unreached language group, from the child's own perspective. No statistics. No guilt. Just a window into a real life, and an invitation to pray.

What we believe
Every language matters
There are more than 3,000 language groups where the gospel has not yet arrived, communities with little or no access to it in the language they actually speak. God's heart is for every one of them, and we believe children can learn to share that heart. Many people call these unreached people groups. Here is why we say it this way.
Kids are never too young to care
When children learn about the world through stories and prayer rather than statistics, something sticks. They don't just know about the nations, they care about them.
