In 2012, one cycle of an ancient calendar system came to a close. Humanity predicted its downfall, but it wasn't the end of their evolutionary climb. It was the beginning.
Willow Kent is discovering that life as a second-phase prodigy comes at a price. Trapped in the London Core, her choices are limited, made difficult by her forbidden romance with Reece and the presence of a new commanding officer who establishes harsh rules.

But when opportunity arises in the form of a mysterious shapeshifter, Willow realizes there's more to her own evolution than meets the eye. She soon learns that keeping secrets is a key move, and the more dangerous they are, the greater her need to evolve into the powerful prodigy nature intended her to become.
But those closest to her have their own secrets, and her status has made her an easy target for betrayal. Who will she turn to, when nothing is as it seems?
