It was interesting that while Emmie felt that her own image left something to be desired, she still refereed to her classmates in unflattering terms like Smelly Kid and Brainiacs (complete with propeller beanies). Kate's depiction is a bit over the top, but we eventually find out why that is. It was nice to see Emmie grow and get over her anxiety, and the character of Tyler was nicely done.
Middle school can be difficult, but it helps if it can be approached with some humor. Invisible Emmie is a great choice for readers who like middle school stories about students struggling to fit in that are combined with pictures. Read alikes for this include Vivat's Frazzled, Wells' Mackenzie Blue, and Barshaw's Ellie McDoodle.
