Astrid travels back to a lost dynasty of China, and becomes Mei.
She was accused of murder in the modern world, but now the dangers that lie in the imperial harem are greater than she'd imagine. Mei is forced to adapt to a world of performance, manipulation, betrayal, forbidden romance, delusions but most of all, defending who you are and destroying those who dares to come in between.
She will evolve.
Meanwhile, the beginning of a lost dynasty that was unknown to the modern world proves to be susceptible to rebellious chaos and damage to the nation's peace.
DISCLAIMER: this is not supposed to be historically accurate...go read a textbook for that!
I repeat: go read a textbook, history nerds.
