No, there still isn't an official English release of the 'Redo of Healer' light novel as of September 2025. I've scrolled through the usual suspects — publisher catalogs, BookWalker, J-Novel Club, Yen Press, Amazon U.S./UK — and the full Japanese light novel run hasn't been licensed and published in English. What you will find are fan translations and patchwork scanlations online; they can be hit-or-miss in quality and legality, but they're why a lot of English readers have read the story at all.
If you're impatient like me, there are a few practical routes: buy the Japanese volumes (they're easy to order from BookWalker JP, Amazon Japan, or import stores), use browser translation tools for e-books, or read the fan TLs while keeping in mind content warnings — the series is notorious for extremely graphic and controversial scenes. The anime brought more attention to the property, but it didn't magically force an English light novel release. I'm still hoping a publisher will pick it up someday, but for now it's one of those titles you either read unofficially or go straight to the Japanese originals. Personally, it's a wild series that I enjoy discussing, even if the official English fate is a bit disappointing.
