Shell Day

I’ve been bursting to reveal my next book (coming May 2026). This special book is a collaboration with my amazing friend and super-talented artist Aaron John Gregory who has created an original, full-page pen and pink artwork to accompany each essay.

The essays peer into the lives of 24 shell-making molluscs (including a few that borrow shells or whose ancestors used to make them) as they go about their days. It’s a global journey, from frozen polar seas to the deep sea, from coral reefs to rocky shores.
