I've had some good success with Mary Lee's children's books. I've not been a fan of all of her books that I've read, but certainly most of them, and this is another winner, not least of which because in a world where women are far too often taught - by everything around them - that shallow beauty is all important, and without it, you're nothing (yes, YA authors, male authors, romance authors, etc, I'm looking at you) this book has the guts to put young girls and science together.
It's a book in the Mia series, and this time Mia is interested in what she can do for her science project. She has several options, and if you read to the end, you can discover two of these which your own daughter (or even son!) can do for herself. Mia makes her own choice as your child can make theirs. The book was fun, easy reading, well-written, and very colorful. I recommend it.
