My new book The Atlas of Deadly Plants is out this week, published by Greenfinch, so I thought I'd celebrate by offering up a series of mini-podcast episodes digging into some of the themes and facts from the book - just in time for Halloween!
In this mini-ep you'll hear a chapter from the book about Abrus precatorius, the rosary pea.

| 0:33.4 | And speaking of audio, if you're wondering where the audio book is on Audible and Spotify, |
| 0:39.7 | well, so am I. It takes a while for it to be approved. It hasn't yet been approved on either |
