I can vouch for Kobo! I bought a Kobo Forma earlier this year and it has quickly become my favorite device. It is both a very competently designed ereader, and not locked into the Amazon walled garden.
Cool thing about Dracula is that, because it is in the public domain, and because it is told through journal entries, it can be read in the real time of the entries. https://draculadaily.substack.com/ is a newsletter that sends you emails of the particular day's entries if you're into that. It's already well underway though, but could be fun for a reread next year
An author whose newsletter I am on, Joshua James, serialized HG Wells' "The War of the Worlds" in the run-up to the release of the first book in his tWotW-inspired alien invasion SF series. A chapter of tWotW was emailed each day. It was fun, especially since the chapters weren't overly long.
I thought that would be a fun substack to set up, sending out a public-domain classic one chapter at a time.
That would be a fun substack! War of the Worlds was the first book that terrified me as a child, to the point that I still can have nightmares of the giant tripod ships, but for whatever reason I really enjoy it!
I was actually thinking more about this today at work (don't tell the boss....)
Dickens published a lot of his work serially. And his stories were wildly popular, like 'Harry Potter' levels of popularity.
It seems like the stories of Charles Dickens would work well for this kind of medium; the only problem I came across is that he didn't necessarily serialize each chapter every week, rather, he would serialize 1-3 (-ish) chapters each week. So breaking the story up as he would have broken it up seems the sticking point.
If I ever do this, and it's not against the rules of c/literature, I'll make a post so people can sign up and get stories emailed to them piece by piece :)
