But when an unexpected attack sends the rescue mission spinning off course, Daisy finds herself confronting danger alone. With Max shipwrecked on a distant shore, her only hope is to find Amazeria: a wild and wondrous pocket of the Greenwild, hidden in the heart of the ancient forest. But time is running out—and with every passing day, the terrible Reaper King is drawing closer. In the shadows of the great rainforest, it’s impossible to know who to trust. Daisy and her friends must draw on every ounce of courage they have to fight for Daisy’s Ma, for the Greenwild, and for everything they hold most dear.
