I flew through this book! This book was thought provoking and clever. I'm not sure I understand some people's complaints about these older sci fi books not having characters that are well developed or relatable. I thought the characters in this were entertaining enough and they all filled the purpose of the idea that the author wants to get across. Some characters exist to fulfill a purpose for an author's idea, others exist for relatable drama. But anyway. 
 The ideas of time and man's relation to other beings in the universe were quite enthralling to me. I was so curious about the Overlord's motives and was quite satisfied with the answer. Feels weird for me to call a sci fi book a thrilling page turner, but there you go. An entertaining yet thought provoking read, and I'm eager to try some of Arthur C Clarke's other books!
