Moving.

Jack, William and Sean are your average teenage boys. Jack, the flamboyant, upbeat happy spirit, the one everyone loved and liked. Sean, the troublemaker and outcast. William, the shy quiet boy that was easy to bully. The only difference is they are triplets.

When they move to Califorina from Ireland, one of the boys find out that Cali isn't as great as it seems.

(I don't know if someone wrote a book like this already. So sorry if it looks like I'm copying them if someone did.)
