(Messenger, Shannon) Shannon Messenger graduated from the USC School of Cinematic Arts, where she learned that she liked watching movies much better than making them. She’s studied art, screenwriting, and film production, but she realized her real passion was writing stories for children. She’s the New York Times and USA TODAY bestselling author of the award-winning middle grade series, Keeper of the Lost Cities, as well as the Sky Fall series for young adults. In Nightfall (Keeper of the Lost Cities Series) (Aladdin), Sophie and her friends face battles unlike anything they’ve seen before. Sophie Foster is struggling. Grieving. Scrambling. But she knows one thing: she will not be defeated. All paths lead to Nightfall—an ominous door to an even more ominous place—and Sophie and her friends strike a dangerous bargain to get there. But nothing can prepare them for what they discover. The problems they’re facing stretch deep into their history. And with time running out, and mistakes catching up with them, Sophie and her allies must join forces in ways they never have before.
