SOLVED. Children's 9-12, girl who wants a stepmum puts an ad about her dad in the lonely hearts

[Hannah]

I read this book around 2010, sort of found it by chance so I don't think it was very popular.
A young girl is being raised by her dad (believe her mum died) and wants a new mum and to find her dad someone. She puts an ad about her dad in the lonely hearts column of a newspaper and then, when someone responds, her dad goes to meet her. The woman that responds ends up being the girl's new stepmum. From memory this was the first of two or three books.

Update: my mum found the book. It's called The Mum Hunt by Gwyneth Rees
