This writer continues to improve. AG Riddle has always been strong on plot development and making a real page turner with just enough of a realistic connection to reality to ease the suspension of reality. With this newest novel, part of a sequence now 3 books long, AG Riddle improves in his character development. His characters are becoming more believable. Note though that’s this skill remains a work in progress. The series provides a believable solution to the Fermi Paradox, hopefully book 3 will take this plot line a little further. Thoroughly recommended.
