As you know by know paranormal lit is not really my thing, but I received a reading copy of Forever and felt obliged to try it.
I haven't read the first 2 books in the trilogy, but the story was pretty easy to pick up. Wolves and teen angst is the short version!
It was well written; quite engaging in fact. The story moves between the four main characters - which allows the author four times the usual opportunities to delve deep inside the heart, soul and psyche of teenage romance and heartache.
The covers of the 3 books are gorgeous and the coloured fonts are a nice touch (but can be difficult to read, especially when tired).
Paranormal lit is still not my thing. But if you loved Twilight and you thought the Bella/Edward/Jacob angst was wonderful and romantic, then Stiefvater's trilogy could be for you.
P.S. There are sexual references throughout the book.
