8-year-old Emma’s dad lives in London with his new wife, but Emma and her mom are just fine as a twosome in their condo – or so Emma thinks.  Needless to say, when Emma finds out that her mother has a date, she is not too pleased about the idea.  Warner’s Emma series is a delightful addition to the world of books for kids who are just transitioning to chapter books, and this sixth installment is no exception.  Emma is a well rounded, believable character: A girly-girl who wants to be a naturalist, a good kid who sometimes makes really terrible mistakes.  Warner’s writing is clever and witty, and intelligently captures the thought processes of her young heroine, and Harper’s black & white illustrations whimsically compliment the story.  Readers will find themselves shaking their heads at Emma’s mistakes, and cheering when she finds a way to fix them.  Recommended for fans of Ivy + Bean and Amber Brown.
