I saw a new book by Ryder Windham that I had not previously heard of as coming out before. It's a walk through the movies and EU from Vader's point of view, going all the way back to his prior slave experience even before Watto, up to his last moments in his son's arms on the Death Star II.
It's held my interest. I'm writing now and thus not reading much but my own work. This one caught my interest though.
So far, I'd recommend it. It comes in a cover jacket that slides off - you can't open it like a book - the actual book's under the Vader helmet sleeve and Anakin's face is on the real book cover - almost like you took Vader's mask off. That's the exact approach this book uses, so I can see why it's appropriate.
