P.D. Singer did an excellent job of writing "Return to the Mountain." The book complements the first four books of the series. I would like to see the author add a couple more books to the series to continue the story, especially of Kurt, Jake along with the others to see how they pan out.
The book, well the whole series held my full attention making it so I was unable to set the book down.
I highly recommend read not just this book but the other 4 in the series.
