Ava desperately wants a pet for her eleventh birthday-but gets way more than she bargained for when she adopts T-A-C-O-C-A-T. When Ava Wren hears about an injured yellow tabby with mismatched ears, she becomes obsessed and wants to rescue him. She even picks out a perfect palindromic name: T-A-C-O-C-A-T. But when Taco joins the family, he doesn't snuggle or purr-all he does is hide. Worse, Ava's best friend starts hanging out with Zara, a new girl in fifth grade. Ava feels alone and writes an acclaimed story, The Cat Who Wouldn't Purr. What begins as exciting news turns into a disaster. How can Ava make things right? And what about sweet, scared little Taco? The New York Times called AVA AND PIP a love letter to language. With this second diary, Girls' Life advice columnist Carol Weston hits another home run.
