This is the sequel to Stay Away from My Sister, and if you haven't read that, you probably should. But since it's so long, I'm putting up a summary for the people out there that are lazy like me and don't want to spend the time reading the first one before they can read the second one.

Everyone at East or West High School in Albuquerque, New Mexico knows that Troy Bolton hates Cam Boucher and vice versa. So when Troy's little sister Mack and Cam's little brother Calum admit that they like each other, things aren't pretty. Troy is determined to save Mack's heart before it gets broken by the enemy and Cam hopes to get Calum back on his side in the Bolton/Boucher feud. But Troy has a change of heart when he gets admitted to the hospital after collapsing at Basketball practice and Cam changes his mind when he learns the real reason why the Bouchers hate the Boltons. When Troy and Cam finally make a truce, the gang ruins it and starts a fight between the Wildcats and the Knights that lands both Troy and Cam in the hospital. After sharing the same room, the boys become friends, but in the mean time,Daniel Boucher is taking his younger son's relationship into his own hands by abusing him. Chad finds Calum barely breathing on his front lawn and calls Coach Bolton. Calum falls into a coma and awakens to find his father has fled and things are relatively back to normal. Then, when West High learns that Cam is friends with Troy and the gang, they revolt against him and he requests a transfer over the summer to East High. Although the year was a little wacky, Mack, Calum and their friends Adam, Bailey, Teagan and Keisha, end the year like any other eighth grader, with the end of the year dance which goes by without anything bad happening (for once.)

So, there is my summary! If you want to read it, be my guest, but if you think you get, by all means just jumps straight into Chapter 1.
