YELVERTON author Lilian Harry is again one of the most popular authors with library book borrowers. Out of 18,763 registered authors, only 201 qualify for the top payment of £6,000 ? the ?ceiling? above which no author can be paid. With borrowings of more than 355,000 during 2004, Lilian Harry falls comfortably into this category ? a position she has held for the past ten years. Also writing under the name of Donna Baker, Lilian Harry?s books are set mostly during the second world war. Her most recent hardback, Tuppence to Spend, outstripped all her previous novels, being borrowed by over 40,000 readers. The sequel, A Farthing Will Do, will be in the bookshops on January 17, and on May 12. Her publishers are launching what is said to be her most powerful novel to date, Three Little Ships ? a story set entirely around Dunkirk.
