Tilly can't believe it when her best friend Matty is asked to be a bridesmaid.

In Tilly's favourite daydream, she's kitted out in the most beautiful bridesmaid dress, walking down the aisle behind a beautiful bride.

The one wedding she'd really like to attend is her own mum and dad's.

But as that's never going to happen, it's time for Tilly to make her own dream come true - and put her bridesmaid services up for hire...A fabulous, funny and moving story about the power of friendship from the mega-bestselling author of Tracy Beaker, Hetty Feather and Katy.

It is full of beautiful illustrations by much-loved illustrator, Nick Sharratt.
