I love going to second hand bookshops or charity shops and browsing the children's sections to see if I can spot any books I used to love reading then?
I used to love anything by Jean Ure, (anyone remember the Peter High school series she wrote?) Anne Digby's Trebizon series, Noel Streatfield, Antonia Forrest's school books with the Marlowes, and endless pony books by Patricia Leitch (anyone remember Jinny and her Arab horse Shantih?) Also went through a serious Sweet Valley phase...goodness knows why, looking back those books were full of fat shaming and bitchiness!
