"Picoult's latest continues her penchant for embracing controversial topics. Each of the well-cast narrators portrays a different character in the novel. As an ensemble, they complement one another without diffusing the story of a family that is faced with the ultimate medical dilemma--whether or not to move forward with the euthanasia of a family member. Luke, a world-renowned wolf species conservationist, has suffered a traumatic brain injury. Now, his grown children must decide the moral imperative between survival and sacrifice--a situation, in principle, that is often faced by wolves. Mark Zeisler's portrayal of Luke is especially poignant as Luke tells his story from the past while he hangs on via life support. As Luke, Zeisler shares a wealth of information about wolf behavior, interaction, and intelligence. The insights into wolf pack dynamics draw striking analogies to the story, creating a strongly unified story and presentation. A.W. (c) AudioFile 2012, Portland, Maine"
