Finding a definitive update on Ana Huang's 'Twisted Games' can be tricky depending where you look. The full, complete novel is absolutely finished and widely available for purchase in ebook, paperback, and as an audiobook. So, if your intent is to read the whole story from start to finish in one go, you're set—platforms like Amazon Kindle, Apple Books, and Kobo have it.
However, the concept of 'ongoing' gets murkier with serialized platforms. Some sites might host it chapter-by-chapter, either legally through subscription services like Scribd or illegitimately on piracy sites, and those postings could technically be 'ongoing' if they're still uploading. My advice is to grab the official, completed version. It's a smoother experience, you support the author, and you won't be stuck waiting for the next ripped chapter to drop. The official translation is just the book itself, no serialized wait.
