Howling Dark (Sun Eater #2) by Christopher Ruocchio ★★★★☆: The deus ex machina was a little much here, but also clearly not necessary from a plot perspective, so I can overlook it at least a little bit. I guess I can see how it paves the road ahead, but I am really stuck on it. I think the plot expansion was useful and enjoyable and I’m looking forward to the next book as we expand more into the Empire itself.
