Following the success of Lemn Sissay's Homecoming, Lemn Sissay returns to BBC Radio 4 with Origin Stories, a comic and poetic look at the treatment of children raised in care, orphans and foster children in popular culture, comparing them with reality. Because it surely says something about how we view them that we create so many for fiction: Batman was an orphan; Lisbeth Salander, The Girl With the Dragon Tattoo, was an orphan; Superman was an orphan and a foundling. Cinderella was a foster child. Darth Vader - well, they can't all be winners.

Lemn will explore the gap between fiction and reality, based on his own experiences of growing up in care as well as those of some special guests.
