'When boisterous big-sister Hester finds her pernickity little-brother Lester sitting sadly in the forest, she's keen to put things right. Making a little brother happy isn't always easy - even with a very active imagination! But as they embark on an imaginary adventure, Lester learns something important. Hester and Lester is about the power of imagination, and a special sibling bond. It's a lovely story - the children are completely engrossed in their imaginative play building a castle out of bits and pieces in the back yard. So engrossed, that they see the castle as real and see themselves as being right in it.' (Publication summary)
