Olive makes a wish that her cat, Henry, could hang out with her all the time like a real best friend. When she wakes up in the morning, he is the size of a human and can speak English- though he's still covered in fur and afraid of water. Olive lends him some of her dresses and they start figuring out how to make this new roommate situation work. He and Olive both work part time jobs, eat pizza, go to parties, and just try to get by. Each chapter is a short story, with new outfits and a new problem to solve. Is the cute boy texting Olive asking her on a date, or is he just a friend? Will Olive ever be able to sell any of her paintings? What will Olive's parents think of Henry? Will Henry ever learn to read, or take a shower? This book is silly, sweet, and charmingly illustrated. I wish I owned half as many cute jackets.
