I think @rescue_toaster@lemmy.zip meant books available within Standard Ebooks, which does not have those Seanan McGuire books. But I wanted to link their fantasy books here in case you wanted to check out some public domain classics:
https://standardebooks.org/subjects/fantasy
Giving a quick perusal, maybe one of these would appeal since you enjoyed McGuire's books:
Lilith by George MacDonald
The Wood Beyond the World by William Morris
The King of Elfland’s Daughter by Lord Dunsany
If you follow those links, there is a nice short description of each along with a touch of historic context.
Wow, they have a ton of Wodehouse. Any suggestions where to start?
