Hazel's theory of evolution

"Hazel knows a lot about the world. That's because when she's not hanging with her best friend, taking care of her dog, or helping care for the goats on her family's farm, she loves reading through dusty encyclopedias. But even Hazel doesn't have answers for the questions awaiting her as she enters eighth grade. What if no one at her new school gets her, and she doesn't make any friends? What's going to happen to one of her moms, who's pregnant again after having two miscarriages? Why does everything have to change when life was already perfectly fine? As Hazel struggles to cope, she'll come to realize that sometimes you have to look within yourself--instead of the pages of a book--to find the answer to life's most important questions"--OCLC.
