...I can't review it because I haven't finished it yet.
What I can say so far is:
This is the first Robin Hood book I can remember reading that worked (mostly) from Tuck's pov.
This is not my favorite Robin Hood book. (Outlaws of Sherwood, by Robin Mckinley)
I think the writing is solid, I'm not so sure about the place-setting, it's not nearly as grim/realistic in sense detail as I tend to like, and man, there's an awful lot of talking in this book.
More, later, I hope. Meanwhile, Christian sf Book tour has some actual reviews.
