The new, revised edition of So You Want to Be a Wizard is finally available.
Diane Duane is updating the first four books in her "Young Wizards" series
to make the timeline fit in with the later books in the series.
The revised edition of the first book in the series is now available
I've just bought it. It's now at the top of my TBR pile. I'll comment when I've read it on how good I think it is.
(I am a fan of the series, so I hope I like the changes. I even have signed first editions of the first three books)
