Zen Ties by Jon J. Muth

Zen Ties - Summer has arrived -- and so has Koo, Stillwater's haiku-speaking young nephew. And when Stillwater encourages Koo, and his friends Addy, Michael, and Karl to help a grouchy old neighbor in need, their efforts are rewarded in unexpected ways. Zen Ties is a disarming story of compassion and friendship that reaffirms the importance of our ties to one another.
