The format is the universal standard for a reason. Unlike PDFs (which are static and annoying to scroll on small screens), an EPUB is "reflowable." This means the text adjusts to your screen size, your font choice, and your lighting preferences.

"Project Hail Mary" is a science fiction novel written by Andy Weir, published in 2021. The book tells the story of Ryland Grace, a man who wakes up on a spaceship with no memory of who he is or how he got there. As he tries to regain his memories, he discovers that he is on a mission to save humanity from extinction.

It is a rare thing in modern science fiction to find a book that manages to be simultaneously scientifically dense and relentlessly optimistic. Rarer still is the novel that transforms a high-stakes extinction-level event into a heartwarming buddy comedy.
