Kindergarten-Grade 2-When Uncle Jake builds Henry a beautiful tree house, there is a big problem-Mudge cannot climb trees. Unwilling to hurt his uncle's feelings, the boy tries staying in the structure for short periods, then getting down to be with his dog. When the grown-ups notice what is going on, they come up with the perfect solution-the tree house is rebuilt in Henry's bedroom so boy and dog can enjoy it together. The family dynamics are sensitive, warm, and funny. Pen-and-ink and watercolor art illustrates the action, and the final spread on which the tree house is next to Henry's bed is just unexpected enough to elicit giggles. A welcome addition to a deservedly popular series.
