How do you shake off a bad mood? Try climbing up the Monkey Walk! On that unpredictable path, you might meet a mischievous (and kind of hairy) stranger. You might go on ridiculous missions. You might even make friends where you least anticipate doing so.

It's a visit to the zoo like no other in Colleen Madden's zany, wholly delightful tale of a big sister whose sour mood is turned around by helping others in an unforeseen way.
