The New York Times seems to dig the new novel, praising his imaginative setting, characters, and metaphors (always the tipping point in a book's purchase, no?).
New York Magazine likes it, although they, too, feel that Chabon was "limited by the detective story’s familiar machinery."
The Boston Globe is a little less effusive, complaining that "too often Chabon's affections -- for the elegant enigmas of chess, for the modern tragedy of the Jews, for verbal acrobatics and literary shenanigans -- turn into a wild display of warring talents, compromising the structural integrity of the novel and turning its hair pin plot twists into a drive off a cliff." Keep in mind, though, that this 'structural integrity' complaint is made in a fifty-one word sentence.
The LA Times gives it a 'thumbs-up', saying that it is "a spiritual descendant of (Chabon's Pulitzer prize winning novel) Kavalier & Clay," and "a book that expands on the sensibility of the earlier novel and its roots in Jewish storytelling."
