Wicked/Son of a Witch
Two of my favorite books. The book Wicked: The Life and Times of the Wicked Witch of the West explains the life of a misunderstood girl named Elphaba who grows up to be known as the Wicked Witch of the West. An awesome book which I highly recommend to anyone over the age of sixteen because there is adult language, adult content, and suggestive items.
Son of a Witch is the sequel to the book Wicked, telling about Elphaba's (the Wicked Witch of the West) "unsure son" (meaning no ones really sure if he is Elphaba's son or not because he isn't green, but know one knows where he came from and he has always been with Elphaba. A sheer mystery), Liir, and his life on finding his half sister Nor which leads to different things such as meeting Elphaba's brother who becomes emporer of Oz, a Quadling girl who gets impregnanted with his daughter, and a council of Birds. Another highly recommended book after you read Wicked and it is recommended once more for adult language, adult content, and suggestive items.
