AMAZING! What is there more to say about this book. I could cuddle up with it all night and be blissfully happy for eternity. Sam & Grace's relationship never seems to amaze me. How Maggie can write exactly how they're feeling and make you feel the EXACT same way is being phenomenal. Authors seem to have a difficult time topping their first book in a series, but not Maggie. Linger was ten times better than Shiver and I definitely cannot wait til Forever comes out.
