I'm not sure quite how much new it brings to an overheated genre, even with the fairy tale motif, but it's tense and exciting, and its fanbase will absolutely love it.
My thanks to the good people at Hodder for sending the book. We also have a review of Pearce's [Sweetly by Jackson Pearce|Sweetly]].
If they prefer their werewolves in a horror/fantasy setting, they'll like [[Witchfinder: Dawn of the Demontide by William Hussey]]. [[Changeling by Steve Feasey]] casts the lycanthrope in a much more glamorous light. This is a little better than [[Dark Heart Forever by Lee Monroe]]. You might also enjoy [[Deadly Hemlock by Kathleen Peacock]].
