The unicorn came to dinner

"The unicorn smells nice, but she is very rude. She never waits for an invitation to come over--she walks right in and tracks heart-shaped hoof-prints across the carpet. She sits in Elizabeth's chair and makes a complete mess of the house. She even sleeps in Elizabeth's bed. [This book] invites kids to talk about feelings--especially worries and anxieties--and, ultimately, about how to be themselves"--Provided by publisher.
