I am loving all of these middle grade books I've been reading recently. I love even more that they are all spooky, with amazing illustrations will make getting a book in your kid's hand that much easier. The Nest by Kenneth Oppel is a psychological thriller written for grades 5-7, and it is super haunting and a little unsettling, probably in a good way.
Steve isn't your typical hero. He's a kid with some serious anxiety and maybe some OCD thrown in there. He's definitely on the spectrum. But anyways, his baby brother is sick which begins to cause stressful dreams for Steve. Dreams about wasps, and their queen, and his only solution, their offer to save the baby. When things start going south, and with actual wasps in a nest at the house, Steven worries about what the wasps will do to his brother. The story is definitely creepy, but there are morals, so I recommend reading the book before your child to help them understand the author's message.
