I reviewed this book a while back, so the sound is a bit different than my normal work.
I like the idea of classifying it as a friendship epic because the story really brings out the connection between the main characters and how they cross the interstellar gap to work together for the benefit of both their words. How that works in later works, we'll have to see.
My site continues to be worked on by a friendly professional from Fiverr. So you might see some disjointed stuff around here. But don't worry; it'll all be good by the end of October.
