Well, the book has completely distorted the epic. Bought it to know more about the epic 'Mahabharata' but left reading it in between.
I suggest you to read BORI critical edition or KMG edition to know more about the epic.
I don't know why this novelist added her own figment of imagination to the epic. Remember it's just fiction. Nothing relates to the real epic by Veda Vyas which is million times better than this.
