The moon is falling.

Born with the gravity majik needed to prevent certain doom, instead of training, seventeen-year-old Syd spends her days skipping academy classes to tinker with airships, ignoring her future as a soldier in the army of the Eichon?the goddess-gifted ruler of the planet. As expected, Syd ends up in the Director's office more often than not, and the academy has had to get creative with its "motivational methods" in hopes that Syd will begin to take her gravity majik seriously.

Luckily, she's untouchable, betrothed to the Eichon's daughter, Adeline. Unluckily, Syd's about to learn she will be the next to take up the Eichon's mantle.

Adeline has been groomed to follow in her mother's footsteps since she was a child. When it's revealed Syd, not Adeline, will become the next Eichon (not to mention do the impossible?save the world), trust begins to break as roles and identities fall apart. Then, when Adeline goes missing, Syd must choose: follow the destiny given to her or find Adeline.

All the while, the looming moon serves as an ever-present reminder of just how small?and thus how big?her problems truly are.
