Ruby Logan has always wanted to be seen. With a trouble-making older brother and a demanding baby sister, she’s invisible in the middle. So when her teacher Mr. Cooper—a cool, funny guy everyone loves—is forced to shut down his YouTube Channel “Coop’s Class,” Ruby’s one chance at feeling special is shot.
