OK I am looking for a book I read around 10-15 years ago:
My recollection is that it had colonists that lived in a wooden stockades for protection against non-sentient dinosaur-like predators native to the planet.
They were also facing invasion from aliens that had the capability to merge consciousness with humans they have captured (I think there was one alien that had merged consciousness with a Chinese human). There was also a large fleet to fleet star ship battle above the colonist planet prior to the aliens landing on the colonist planet. I think the book pretty much ended at that point.
