Written and illustrated by Kevin Henkes

Ruthie Simms didn't have a pet, or a sister, but she had Jessica, and she was much better.

Jessica does everything with Ruthie. When Ruthie eats, Jessica is hungry too. When Ruthie makes a mess, it is Jessica who was clumsy. When Ruthie's parents go out and leave a babysitter, it is Jessica who gets a tummy ache and needs them to stay home.

'There IS no Jessica', her parents insisted, but Ruthie knew better.

And then Ruthie starts kindergarten, and her father suggests she leave Jessica at home for the day. Of course she does not. Of course she spends the day whispering quietly to her Jessica, scared. BUT. BUT BUT BUT then she makes a new friend, and guess what her name is? This is how we discover that Jessica is real, something Ruthie knew all along.

So: Henkes's illustrations in this book are delightful watercolor and pen-and-ink drawings that draw you right into Ruthie and Jessica's world. He even includes small handwritten cartoon dialogue, small tender conversations and confidences. Lovely crisp narrative. Small manageable plot twist for the children. Happy ending for the children. And a warm mush spot in my heart for this book.
