Read: Orphaned Worlds
Cobley keeps up with the pace of Seeds of Earth. Yet, the second book in his “Humanity's Fire” trilogy losses some appeal compared to the first one.
Orphaned Worlds has too many battles and too many unnecessary technical details in their description. In contrast to the first book the various plot lines feel diverging, the size of the cast results in some confusion. It is a bit strenuous to keep all the different persons and plot lines in mind. Killing a character and bringing him back is fine, doing it twice is not. And ending the book with even multiple cliffhangers is really a turn-off.
Still, good enough.
