I've always been baffled by books that are put out with spoilers in the blurbs – like mysteries telling who the victim in chapter 5 is going to be – or even in the jacket art. Putting one in the title, though, is even dumber than having a title which actually means little to the story (thinking of Across the Nightingale Floor here). On page 172 of Lord of the Wolfyn (about which title I wondered, since the main character is many things but not Lord of the Wolfyn), something happened which made my eyes flick up to the title, and I thought "Ah. Well, I know how that's going to come out, now, don't I." At which point I rolled my eyes and skimmed for awhile.
Apart from that, it was an, I think, above average paranormal romance (PNR), though surprisingly undersexed if anything. That is not, I should add, a complaint. It has an interesting premise, and interesting worldbuilding – I actually love and am intrigued by the concept of the three worlds linking, intrigued enough that I may one day seek out the other book in the series (one for each sibling – this was #3). Each seems to be a take on a different fairy tale, this one being Red Riding Hood.
