Ra

Ra is a tremendously well-crafted story on a scale far-larger than it initially seems, made all the more impressive by its serial release nature. Sam Hughes' works should go down in history alongside Asimov and Sagan.

I'm a big fan of qntm, this book has the their trademark wildly unique world. But the story got a little too big in the final third and I felt like it kinda fizzled out some. Recommended if you like the genre.
