I bought the POD copy (dont like PDFs) and am exceptionally happy with the content. The thing i liked the most about it was that it seems nearly plug and play into any campaign you're running. Is there a local alchemist in this town? They could know about the garden and once they trust the Characters... BAM - instant adventure.
I dont think I'd be smart enough to use this book and generate the gardens at the table, I'd be more likely to generate 5 to 10 pre-session, put them on an A4 sheet each then randomly select one when they go deeper.
I need to read it again, because I was not 100% sure how the "go deeper" mechanic worked narratively- are there meant to be hedge tunnels leading away on the sides/back of each garden that the players can just dash to? Either way though, it was a great read i consumed over 2 nights and want to include in my next game.
A few typos let the presentation down, but the content and tables were so good that I highly recommend this book to anyone that wants a few session adventure in an extra-dimensional garden. 9/10 so good.
