Green Grows the Holly: Medieval and Renaissance Christmas Carols Arranged for the Harp

I've been looking for Renaissance Christmas books for either guitar or piano and the only one I found before this book wasn't very good. But then I found this book and am very happy it exists. I just wanted something very simple with simple songs and arrangements and I found it in this book. I don't play harp but I play piano and guitar. Right now I'm playing the songs in the book on piano and they sound very good. I'm definitely going to be playing these songs this Christmas.
