Three years ago Alex Hill, Luke Hemmings, Calum Hood and Michael Clifford were inseparable. Three years ago, they were each others best friends. Growing up together, it seemed like they were always as close as they were and there's nothing that'll change that.

It's been three years and a lot have changed since the day Alex moved away but now she's moving back to Australia and she's about to find out just how much things changed while she was gone.
