I this novel read back in 2013-2014. The context basically composed of a near future, where mankind had made contact with an advanced alien species. These aliens passed down technology in the form of a brain implant that was located in either the right or left temple (humans also had the choice of having the implant or NOT) that would store your memories/consciousness and then after you died, this implant would become warm and hum/vibrate. Your body was picked up and your implant would be beamed up these huge light towers. Then you would be resurrected to "explore the stars" with these aliens. You would be able to see your resurrected loved ones in a "room" before they left for good.
There were multiple characters with multiple story lines. I enjoyed the book so much I wrote down every character and backstory on the inside of the paperback cover. The title of the book was the same name these aliens called themselves. It was something like "Kathani", but I'm not sure.
