How far would you go to save the world?
When Maisie Danger Brown nabbed a spot at a NASA-like summer boot camp, she never expected to uncover a conspiracy that would change her life forever.
And she definitely didn't plan to fall in love.
But now there's no going back-Maisie's the only thing standing between the Earth and annihilation. She must become the hero the world needs. The only problem is: how does a regular girl from Salt Lake City do that, exactly? It's not as though there's a handbook for this sort of thing. It's up to Maisie to come up with a plan-and find the courage to carry it out-before she loses her heart . . . and her life.
Equal parts romance and action-adventure, this explosive story is sure to leave both longtime Shannon Hale fans and avid science fiction readers completely breathless.
