The novel “Take Back the Sky” by Greg Bear was published for the first time in 2016. It’s the third book in the War Dogs trilogy and follows “Killing Titan”.

Master Sergeant Michael Venn and a group of Skyrines – Sky + marines – discovered at least some truths about the aliens known as Gurus and the support they’re providing to humans in the war against the Antag (Antagonist) aliens. The consequence is that they risk having to fight other humans who are convinced that they’re traitors.

For Michael Venn’s group, the only hope of achieving peace in the solar system is to continue their journey to the Kuiper Belt and the mysterious Planet X. New fragments of information that include those about the solar system’s remote past are always likely to cause greater alienation. Only direct contacts with the Antags can bring crucial pieces of a puzzle that will determine the future of various species.
