This was utterly engaging from start to finish! I've not particularly been very interested in mushrooms before (never even ate them until a few years ago) and this still captivated and inspired me with every single page.
I recommend the audiobook, especially. Merlin Sheldrake narrates and really makes the subject come alive with his voice. Sounds like....a really......fun g--

4.5 rounding up for how it handled the genre tropes, for the most likeable protagonist I've come across in a while, for Silvia Moreno-Garcia's absolute unflinching prose, and for the ending, such as it was, for making me scream into my hands.
