Seventeen-year-old Kat Hartland loathes Unrequited, the world's biggest boy band. Is she the only girl in Sydney who can't be bothered with perfect-looking Angus Marsden?

Give her 5 Seconds of Summer. Now.

Or maybe the seriously-hot med student who rescued her on a train-and who could be Douglas Booth's twin! Perfect formal partner, much?

But when Kat comes face to face with Angus Marsden himself, things start to get complicated. Very. Throw in a deranged female popstar, final exams, a part in the musical and a mum who just doesn't get it-and where is her best friend?

When did life get so crazy? Kat's just an ordinary schoolgirl.

Isn't she?
