Of the indie books they reviewed (thousands?), IndieReader selected Nemo’s World as one of the 56 best of the year 2015:

A group of idealistic scientists use gateway technology to save the United States in NEMO’S WORLD By Jeb Kinnison
The second installment in Jeb Kinnison’s The Substrate Wars series takes place in the near future where the US has become a one-party oligarchy opposed by a group of rebel scientists and humanity is poised to destroy itself in the name of “security.”

Here’s their review:

5 STARS
IR Verdict: Good science fiction is usually about humanity rather than deep space or death rays. NEMO’S WORLD is well-written science fiction that harkens back to the golden age of Heinlein and Asimov.

If you haven’t read the first in the series, it’s free until Friday: Red Queen: The Substrate Wars 1.
