Blue Wolf by Catherine F. Creedon (2005, Paperback, Reprint)

Life has been difficult for Jamie Park since his mother died. While he finds some level of comfort running on his track team, the absence of his workaholic scientist father only makes life more complicated. Then one day Aunt Louise, a relative whom Jamie has never heard of, invites him to spend the entire summer with her in her isolated mountain home in the Pacific Northwest. Jamie accepts the offer, and his adventure of a lifetime officially begins.
Upon his arrival, he quickly finds out that life is going to be quite different. Louise's dwelling place is a one-room cabin with no plumbing or electricity. Despite this, Jamie excitedly listens to his aunt's nature and survival lessons. A number of peculiar events soon transpire, causing Jamie to be conscientious of an alliance he feels with a neighboring wolf pack. He then learns the truth behind the visit and a major secret about his family. Will Jamie return home, or will he stay with his aunt?

If I were Jamie, I would have decided to come home because I would have missed my family and friends. If you enjoy reading books with animals and a plot containing elements of mystery, be sure to read BLUE WOLF to find out what happens to Jamie and his family.
