Things stay interesting at Tool High. Haleigh is adorable, and the object of Mack’s affection. But Haleigh is more interested in Luke, Mack’s cousin. So, Mack is sleeping with Adrianna, his now-stepsister. (But they were starting sleeping together before their parents got married, which somehow makes it not weird.) Adrianna is done with Mack, but keeps falling back into the same habit. And Piper, well… She’s just trying to stay alive.
