If you are looking for a conclusion to the saga of seven suns, you will find one here. But unfortunately, the first question I asked myself after finishing it was “…did the author just give up?”
For example, those aliens of darkness they've been going on about for six books? Never appear. Never mentioned. Never resolved. Origins of the four main elemental races? Barely discussed. Repercussions of this great war? Bah, who needs them.
All the plot threads that relate directly to the main characters are resolved, and the series comes to a reasonable conclusion, but certain plot elements just dissapear, or are completely written off.
If you're looking to finish the series, it'll give you an ending… but not a good one.
