The second book in Maggie Stiefvater’s Wolves of Mercy Falls series begins as Sam remains a human enjoying his time with Grace as much as he can. In Linger, we hear much more often from Sam than Grace, as well as from Isabel and a newcomer, Cole, who turns out to not only be one of the wolves Beck had changed in book one, Shiver—but he’s not without his problems.
Grace’s “missing” friend who is really a turned wolf, managing the new wolves Beck infected—including two rock stars—and dealing with Grace’s dubious parents are all on Sam’s plate this year, as is the fact that brilliant Grace is ready for college while he is still getting used to the idea of living as a human for the rest of his life.
Another contention to deal with in this book is Isabel’s father, who wants to kill as many of the wolves as possible after the death of his son. But the main issue in the book is really Grace’s mysterious illness, which is burning her up and eventually bleeding her out.
