In this high-stakes duology closer from New York Times bestselling author Margaret Peterson Haddix, Maisie finds out she's the last moonleaper--unless she can figure out how to change past events to secure the moonleapers' legacy.
Maisie was thrilled to become a time-traveling moonleaper and help her Great-Aunt Hazel fix the past--catapulting everyone in the world into a better timeline. But now Hazel's gone, time is glitching, and the only other moonleaper Maisie knows appears to be in grave danger.
Then a mysterious boy named Krieger shows up. Maisie is immediately suspicious because he seems too interested in her secrets. But as it turns out, he has a few secrets of his own. Could working together be the key to fixing time and saving Maisie's friend Ainsley--or will that doom all of humanity to an unbearable future? The clock is ticking, and it's up to Maisie make things right. Or else the moonleapers--and Maisie herself--could be erased from time...forever.
