Emily Barr popped by the studio for a chat with Penny Smith about her new book.
The One Memory of Flora Banks tells the story of a teenager with the inability to make short-term memories after a brain tumour was removed.
However, when she kisses a boy, this is the one memory which remains with her.
Barr, a travel writer and journalist whose career began after the 2001 publishing of her hit novel Backpack, popped by the studio to chat with Penny about the novel.
She said: "I love books about memory. That's why I wanted to write one.
"I think when you're writing fiction, it's so exciting to have someone, somewhere, not knowing why they're there, what they're doing, or where they're supposed to go next.
"Then they gradually piece it all together, and with Flora, she does this several times a day.
"I love it, because she's the definition of an unreliable narrator. The reader will know more than she does.
"There's all kinds of mysteries to solve."
