Yes, indeed there are other reading events besides March Magics, and here they are.
Paula at Book Jotter is hosting Dewithon 2019, also known as Reading Wales. Read anything by a Welsh writer, or about Wales! My trouble is, all the Welsh books I can find are fantasy novels I've read before, but I have this copy of Elidor, by Alan Garner, that I haven't read in a long time, and also Jasper Fforde wrote a fantasy trilogy I haven't read yet, so I got The Last Dragonslayer. I plan to enjoy those, and sometime I will get my hands on some Serious Welsh Literature.
Cathy at 746 Books is hosting Reading Ireland 2019. She's even going to have weekly themes! It so happens that I put a battered old book of Yeats on my TBR list for Adam's challenge this year, so I'll read that. Looking into it properly, I find that it contains Stories of Red Hanrahan, The Secret Rose (also a collection of stories), and Rosa Alchemica -- a novella perhaps? I really have very little idea of what is in this book, and was pretty surprised to see a publishing date of 1914 when I inspected it just now. It's pretty elderly but I didn't think it would be that old. I've never read anything by Yeats that wasn't poetry, so we'll see how I like his prose.
