Wolf Stalker is one of those books that you can't find anything bad to say about, but it's not Newbery award material. It has some charm to it, with somewhat interesting characters with whom you can relate to, accompanied by a nice, stable plot, but it doesn't stand out from the hundreds of thousands of books out there, and it'll probably never think about it now that it's done and read. You're being too harsh, you say, what with the plot being about saving a supposedly-bloodthirsty wolf, uncovering secrets, a grumpy foster kid, and an evil dude, but even with all those features, Wolf Stalker just isn't phenomenal or mind-blowing, although it does have a good message about preserving the world we live in and the animals that live in it with us. I liked it, and I'd say ages elementary through middle school will enjoy it.
