Book 1: Sector Eight Book 2: Beyond Death Book 3: New Contract (oops, this one is still processing by Amazon)
By the way, we're working on translation of the last (4-th) Perimeter Defense book. By the end of 2017 you'll have another complete Sci-Fi LitRPG series.
We prepared second edition of paperbacks for two series:
Mirror World by Alexey Osadchuk and Perimeter Defense by Michael Atamanov
Every book now has its own ISBN code, so it kinda feels like we are getting from junior publishing into professional league. And it feels awesome!
