Don't Eat the Soup! (Grim Falls Academy, 1) by Louise Forshaw

Welcome to Grim Falls Academy! 

Something weird is happening at Grim Falls Academy... and that's saying something for a school for supernatural kids! 

In the series opener, something strange is stirring in the school kitchen: the meals are more monstrous, the headmaster is barricaded in his office, and the teachers are losing control of their limbs!  With the looming visit of the dreaded school inspector, newly confident werewolf Seb, his nervous vampire best friend Victor, and the mysteriously powerful transfer student Tabby must uncover what’s corrupting the faculty and do it before everything gets totally out of control! 

Don’t Eat the Soup! blends spine-tingling humor with creepy mystery and introduces a cast of unforgettable characters while setting the stage for bigger supernatural mishaps ahead.
