At an isolated campground called Moon Shadow, thousands of eager skywatchers have gathered to witness a spectacular total eclipse of the sun. But the rare astronomical event is not the only major shift happening in the universe today. You will experience this unforgettable weekend through the eyes of three very different teenagers whose lives are about to collide. Ally feels completely at home among the stars, comets, and quiet nature of the campground, and she is terrified of leaving it behind. Bree is a popular, glamorous girl who uses her perfect image to hide her true anxieties from the world. Meanwhile, Jack is an awkward, quiet boy who is used to staying out of sight and spending his time entirely alone. As the sky darkens and the stars reveal themselves in the middle of the day, you will watch these three strangers form unexpected connections. Through their shared awe of the cosmos, they will discover how to step out of their comfort zones, embrace new friendships, and find their own unique places in the vast universe.
