IndieReader picked Shrivers as one of its “19 Great Indie Books for Spring:”

Humanity’s attempt to survive first contact with a civilization that reaches back to the early days of the universe in: SHRIVERS

BY JEB KINNISON

    

Humanity has finally found peace among the stars thanks to quantum gateway technology, replicators, and powerful AIs. Before the dust can settle, the riddle of the Fermi Paradox is answered in the worst way possible.

Meanwhile, the first in the series, Red Queen, got a new Amazon review:

4.0 out of 5 stars
A nice mash up of science fiction, politics and economics
By Dave Carveron March 30, 2016

I try to avoid books that can’t be tied up in a single volume. However the blurb on this one looked like it was worth reading at least one. I’m glad I did as volumes two and three are now in my kindle queue.

It’s spring 2016 as I write this. There is craziness at Emory University and across the Ivy’s; and you can extrapolate that nonsense right into this storyline. There is terrible news from around the world as bombings are becoming more frequent; and you can extrapolate that reality right into the storyline. Now add in some interesting physics and a few “star trek” nerds and computer scientists and you get a great story that turns out to be too big for just one book. I’m glad I took a chance on it.

Somewhat reminiscent of the interstellar enigma series.

…which I haven’t read.
