Is it Groundhogs Day?
Format: Kindle
Trapped in Class is Book 1 in the Video Game Elementary by Scott Charles. This book was written for Middle School ages, but, being a Senior Adult, I LOVED It!! This book was pure fun, action and adventure. It must have been Groundhog day because Connor Lamb has been reliving his school day over and over. He, along with the school custodian, Glitch and friends, fight Fanged Slime, Vampire Mold and other monsters. I believe that this series will be a home run with students and the young at heart.

A book reluctant readers will love
Format: Kindle
Kids who are Minecraft fans will love Scott Charles’ Trapped in Class, Book 1 of the Video Game Elementary series. Connor is a fourth grader at Video Game Elementary, an online elementary school built inside a fully immersive virtual reality video game. Connor’s watching the clock, waiting for school to end so he can go to his first practice with the Swords Team when suddenly there’s a strange hiss, bleep, crack, and the world fades into white. The next thing Connor knows, it’s morning again. Like some weird, middle school version of Groundhog’s Day, the day has restarted. Stuck in a time loop, Connor must fight Fanged Slime, Vampire Mold, and other monsters to keep the school’s power crystals from being destroyed. Luckily, he has a school custodian, a friend named Glitch, a girls who’s very good at hacking the system, and a cleaning ghost with an attitude to help him. This book is easy to read and action packed. It should be a great hit with kids who’d rather hold a game controller than a book.
