Now a children’s author, in lockdown Anne started Refuge In Literacy UK as a CIC, but runs as a charity, to encourage authors and publishing houses to donate copies of their children’s books to families in domestic violence refuges.

Anne also devised reading prompts from birth to 11years old to help parents ask the right sort of questions enabling children to develop higher order questioning and answering. These reading prompts feed into the comprehension strategies teachers are using throughout early years to the end of primary school, thus preparing the children not only for KS2 SATs, but also year 7 in secondary school.

Working with many organisations including the Soroptimists, Refuge In Literacy UK has 9 pilot refuges throughout the country   working in a variety of ways with the reading prompts, with impact and success.

It is the aim of Refuge In Literacy UK to encourage, with help from the Soroptimists, as many refuges throughout the UK to use the reading prompts not only to help children’s reading and higher order thinking skills, but also to help parents develop more confidence and self- esteem thus improving their life chances.
