At its heart, this is a book about the bond of sisterhood, how deeply we can love, and how far we will go to protect those we cherish.
Channi and Vanna are sisters, and the only ones in their family who love each other unconditionally. Vanna was born with a great light and beauty, whereas Channi was offered as a sacrifice by their own father, and escaped but wears the monstrous visage of a snake. When Vanna is to be auctioned off by their parents to be married to the highest bidder, Channi is the only one who can compete and save her sister from the cruelty of both their parents and Vanna's suitors.
Imagine if Elsa and Anna from Frozen were thrown into the world of Beauty and the Beast, with a dash of the trials from the Hunger Games. I am obsessed with this book and highly recommend everyone read it.
