Madeline Miller is an award-winning American novelist known for "The Song of Achilles" and "Circe". Her books became bestsellers within weeks, and she has worked as a Greek and Latin teacher while writing "The Song of Achilles". She lives in Pennsylvania, the United States of America.

"Circe," tells the story of the daughter of Helios, the god of the sun and mightiest Titan, called Circe. Circe is neither the look nor the voice of divinity and is rejected by her kind. While isolated, she turns to mortals to have at least a bit of companionship. Therefore she discovers her power which is forbidden for god: witchcraft.
When Circe falls in love with a mortal, she asks her grandmother to turn in immortal. She learns that her crush has died to marry another nymph called Scylla as the dead is done. Through her pure jealousy, she transforms the nymph into a various headed monster. Zeus banished her for her regretful Baha'i or to the ornate island of Aiaia.  There she perfects her craft and draws on the strength of nature itself. 
However, she is not always alone; many are destinations to visit in her exile, like Hermes, Daedalus or wily Odysseus. 
In the end, Circe has to decide which side she chooses; the gods or the mortals she grew to love along the way. 

This novel was written in the first-person narrative in the past tense. Everything happens in Ancient Greece on the many islands. 

In the second half of the book, Circe has been alive for more than a thousand years. She becomes more thoughtful about her experiences during many interruptions and when Circe's story takes a darker turn. At those junctions, Miller is thoughtful and reflective. In the book's more sad moments, the author explores Circe's loneliness, alienation and how her experiences or misunderstandings may have warped her perceptions. 
Through the bond of the gods, Titans, Olympians, lesser gods, mortals etc., the book studies the significance of having power and how it is derived, affecting how people associate with each other. Moreover, using a variety of classic Greek Legends to tell a story provides an excellent base and a wide situation to delve into important questions about morals and goodness and pragmatism and ambition and coordinating it all with the requirement to survive and protect yourself.

Overall, I Did enjoy the story; however, I didn't anticipate a bit. I had to understand Greek mythology so much before going into this. If you don't know anything about mythology, do yourself a favour and google a bit before bed; however, the writing is the bomb, and I would highly recommend reading this.
