Perfect for fans of The Thing About Jellyfish and Raymie Nightingale, this tender middle grade novel from Lisa Jenn Bigelow, acclaimed author of Drum Roll, Please, follows a precocious girl whose life is turned upside down in her last year of middle school.

Hazel knows a lot about the world. That’s because when she’s not hanging with her best friend or helping her two moms care for the goats on their farm, she loves reading through dusty encyclopedias. But even Hazel doesn’t have answers for the questions awaiting her as she enters eighth grade. How can she make friends in a new school where no one seems to understand her? 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 answers to life’s most important questions.

Hazel’s Theory of Evolution is a genuine, thoughtful, and ultimately uplifting novel about learning to flourish no matter what changes life throws your way.
