This is book 1 in an intermediate elementary/middle school series. There are two books so far. I have to tell you after reading a few flops in a row, this book was really good! I'm excited to introduce it to my 4th and 5th graders. It is great for those that love a good fantasy fiction story. Adventure and of course, if you are an animal lover, how could you resist. Your imagination will wonder what animal would be your spirit animal. I highly recommend this for the 4th grader and up.
Summary from goodreads.com
Four children separated
by vast distances all undergo the same ritual, watched by cloaked
strangers. Four flashes of light erupt, and from them emerge the
unmistakable shapes of incredible beasts - a wolf, a leopard, a panda, a
falcon. Suddenly the paths of these children - and the world - have
been changed for ever. Enter the world of Erdas, where every child who
comes of age must discover if they have a spirit animal, a rare bond
between human and beast that bestows great powers to both. A dark force
has risen from distant and long-forgotten lands, and has begun an
onslaught that will ravage the world. Now the fate of Erdas has fallen
on the shoulders of four young strangers ...and on you.
