So I'm starting on the prequel to my first book now, and have come to a bit of a conundrum. My first book is from the perspective of the heroine and protagonist of the series. I am now thinking of making the prequel from the perspective of the antagonist/villain. But I'm worried it may trip up readers. The thing is, the prequel is mostly about how and why the villain became who he is, and why he attacked the kingdom of the heroine in the first place. So would this difference in the two books, really be that big of a deal?
