What is this book, even? It's hard to tell. So little happens. Similar to book 3, the entire story could have been told in about a third of the book. There are just too many characters here, many of which don't add any significant insight to the story (Clarissa... 🙄) and just drag out the end forever. Everything important literally happens in the last 3 chapters of the book. Way too many things remain unexplained, like

Spoiler

the whole thing with the disappearing ships and why that's even happening. I still don't know the reasons for the great mystery behind the alien races and planets. And I miss Miller (seriously). Is that stuff ever gonna be explained? *sigh*

. I hope eventually it will have been worth it reading these books, but I have the suspicion that I won't find out until 2019.
