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.
