US actress and singer Hilary Duff has been signed up by Simon & Schuster UK.
The firm will publish two titles in Duff's young adult fiction series, as well as a non fiction title. The first novel in a multi-book deal - Elixir - will roll out in October 2010.
Following in spring 2012 will be Duff's non fiction title which tackles the challenges faced by children of divorce.
Ingrid Selberg, children's publishing director at Simon & Schuster UK, said: "Hilary Duff is an international sensation and we are confident that her debut into young adult books will be a fantastic success. Elixir is an accomplished page turner and we are delighted to be able to give Hilary's fans the opportunity to connect with her in an entirely new way."
