It was my first Arthur C. Clarke book. And even though it is a classic I didn't have any spoilers before I read it. The idea of finding an unknown object in the sky with extraterrestrial suspicions, and going there to actually explore it was very thrilling. And well, it is hard sci-fi, so I expected a lot of scientific explanations and musings on the laws of physics.

I had some hard time trying to imagine the interior of Rama. The scale and complexity of what was inside was very difficult for me to grasp. But I tried to imagine Rama like "The Citadel" of the video game "Mass Effect", at least to understand the cylinder design of the spacecraft.

I really expected there would be more answers in this book about the purpose of Rama and the "biots" inside. Of course, the author leaves a hint at the end indicating that there is more to the mystery.
