Claire North is a pseudonym for Catherine Webb, a Carnegie Medal-nominated author whose debut novel was written when she was just fourteen years old.

The follow-up Touch received widespread critical acclaim and was described by the Independent as 'little short of a masterpiece'. Her next novel The Sudden Appearance of Hope won the 2017 World Fantasy Award for Best Novel, and her recent book The End of the Day has been shortlisted for the 2017 Sunday Times/PFD Young Writer of the Year Award. She lives in London.
