SHANNON MESSENGER'S Middle Grade Series KEEPER OF THE LOST CITIES Her New Book STELLARLUNE

Shannon Messenger is 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.
Her new book is Keeper of the Lost Cities: Stellarlune. In this stunning ninth book in the Keeper of the Lost Cities series, Sophie and her friends discover the true meaning of power-and evil.
Shannon's protagonist Sophie Foster changed the game. Now she’s facing impossible choices:
when to act, when to trust, and when to let go. Her friends are divided and scattered, and the Black Swan wants Sophie to focus on their projects. But her instincts are leading her somewhere else.
Stellarlune-and the mysterious Elysian-might be the key to everything. But finding truth in the Lost Cities always requires sacrifice. And as the Neverseen’s plans sharpen into terrifying focus, it appears that everyone has miscalculated. The Lost Cities’ greatest lie could destroy everything. And in the battle that follows, only one thing is certain: nothing will ever be the same.
The world and characters that Shannon creates immediately suck you in--but everything is still grounded in a relatable story. The stories feature a strong female protagonist as well as several great male characters/friends, and they're full of action, humor, and fantastical elements, which will appeal to all readers. Millions of readers have made Keeper of the Lost Cities a worldwide phenomenon, and the series continues to grow with each new book.
