Wicked author Gregory Maguire is writing a new book in the series based on Glinda, according to Harper Collins.
A statement on the publisher’s website says that Galinda: A Charmed Childhood will focus on the “pink-clad, effervescent” Galinda Upland, who later becomes Glinda the Good. It is a sister volume to Elphie: A Wicked Childhood, which was released earlier this year.
