Personally, I did not care for Shiver as much as I had hoped to. I found Grace and Sam's obsession with one another pretty absurdly disgusting. I suppose their are couples that want to be together 24/7/365, but they probably are not people I would want to know. This book, though, was better from the addition of Cole and Isabel's perspectives. Cole and Isabel are both sarcastic and cynical, so reading their thoughts was much more enjoyable for me than reading the love-soaked longing of Grace and Sam.

One more awesome thing about Linger: the text of the novel is green. Made me realize how awesome it is to not be reading in black and white for a change, which is rarely possible with books. That was an awesome decision on the part of the publisher, although I wish they had done Shiver in blue, so that the series was consistent.

The ending indicates that at least one more book will be coming in this series. Here's hoping that Cole and Isabel keep getting a larger portion of the book. Recommended for fans of the first book. If you're wondering whether to start the series, I might wait and see how people review the series as a whole, as I am still not entirely sold on it.
