The EPUB (Electronic Publication) format is the industry standard for ebooks, and it is particularly well-suited for Project Hail Mary for several reasons:

Project Hail Mary is dense with diagrams, scientific equations, and internal monologues. EPUB files automatically adjust text to fit your screen—whether you are reading on a 6-inch Kobo, a 10-inch iPad, or a 6.7-inch smartphone. You can increase font size for late-night reading without horizontal scrolling.

Andy Weir’s publisher (Ballantine Books) sells DRM-protected EPUBs through multiple retailers. Do not use pirate sites – you risk malware, poor formatting, and harming the author.

| Source | DRM? | Notes | |--------|------|-------| | Google Play Books | Yes (Adobe DRM) | Download as EPUB, transfer to ADE-compatible devices. | | Kobo | Yes (Adobe DRM) | Clean formatting; often has sales. | | Apple Books | Yes (FairPlay) | EPUB-based but locked to Apple ecosystem. | | Barnes & Noble Nook | Yes | Good for Nook devices/app. | | Eden Books (DRM-free) | No | Occasionally offers DRM-free indie or reverted rights, but Project Hail Mary is usually DRM-protected there. | | Public Library (OverDrive/Libby) | Yes (temporary) | Free; borrow EPUB sent to your device or app. |

Note: Amazon Kindle does not use EPUB natively, but you can convert their AZW3 file to EPUB using Calibre (requires removing DRM, which may be legally restricted in your region).
