Oh, definitely, though the approach changes a lot depending on what kind of reading experience you're after. The trilogy is so mainstream that most major ebook retailers and library apps have them.
I usually go through the Libby app with my library card; I can borrow the whole ebook or audiobook. That's straightforward, no chapter hunting. But if you specifically want a chapter-by-chapter, website-style read, some of those web novel or serial reading platforms might have it, though you'd need to check if it's an authorized version. I know some apps that host fanfic and original works sometimes have 'inspired' stories, but for the official text, buying it on Kindle, Apple Books, or Google Play Books is the most direct way. You can still jump chapter to chapter there.
Personally, I find those reading apps better for discovering new indie series that update weekly. For a finished blockbuster like this, grabbing the whole thing just feels simpler. The chapter-by-chapter thing works better for ongoing stories where the anticipation is part of the fun.
