The Unknown Bridesmaid. by Margaret Forster — Margaret Forster

When Julia was eight, she was asked to be a bridesmaid at her beautiful cousin Iris's wedding. Her mother saw this as a chore, but Julia was thrilled. When the time came, even the fact that her bridesmaid's dress didn't fit, and was plain cream rather than the pink she'd hoped for, couldn't ruin the day. But after this, things began to go wrong for Julia, starting with an episode involving her cousin's baby, a pram, and a secret trip round the block.
