Life is complicated enough already, but when you try to solve your big sister's relationship problems, it can only mean trouble!

Rebecca isn't looking forward to school after a summer full of music and excitement. To make it worse, her most annoying classmate Vanessa gets the starring role in a new ad campaign: now she's going to be on television, on posters, on the radio and even in the charts!

Luckily a new arts and music studio space for teens has opened up where Hey Dollface and their summer camp friends can practise.

Then Rebecca's sister Rachel is dumped by her longtime boyfriend Tom, and Rebecca is determined to cheer her up.

Throw in a dad who is trying to take over his amateur musical, a mum who keeps reminding her that it's a big exam year, and an English teacher who has decided to become a novelist, and it's another eventful term for Rebecca.
