A year ago, Rachel Bird hated it in small-town Aspen Lake. She and her little sister, Jane, had just moved in with grandparents they never knew they had. But this summer looks very different. Rachel has a best friend, a boyfriend, and she gets to ride her horse, Magic. They are all sweltering under a heat dome, and though Rachel's heard about the dangerous wildfires, they seem very far away.
Then the grass turns yellow and Rachel smells smoke all the time. Just when she was finally letting herself settle in, her new home is in jeopardy. If the fires reach Aspen Lake, will Rachel and her family be able to make it out in time? And what will happen to everything they leave behind?
