It was 1964 in the brand-new state of Alaska, a vast land of staggering beauty and heart-stopping dangers. Eleven-year-old Jack had grown up living happily with his parents in an off-the-grid cabin, miles from their closest neighbors. Grizzlies and wolves outnumbered people, and dark winter days were 30 degrees below zero. Jack had always thought of himself as strong -- “Alaska tough”. But then the most powerful earthquake in American history -- the Good Friday Earthquake -- struck.

The 9.2 magnitude quake lasted nearly five minutes, destroying downtown Anchorage and sending 30-foot tsunamis into coastal cities, wiping out entire communities. Its vibrations were felt around the world. In the end, it caused billions of dollars in damage and the death of 129 people.

When her fifth-grade teacher hints that a series of lessons about home and community will culminate with one big answer about two tall towers once visible outside their classroom window, Deja can't help but feel confused. She sets off on a journey of discovery, with new friends Ben and Sabeen by her side. But just as she gets closer to answering big questions about who she is, what America means, and how communities can grow (and heal), she uncovers new questions, too. Like, why does Pop get so angry when she brings up anything about the towers?
