1: Human Man by Refusenik As the sequel to "Human Phoenix," there was an immediate imperative for me to read this story. The story features the same main character - Scott MacIntyre - who's been irrevocably altered by his experiences between the two stories. You want to know what struggles he still faces from the first story and how they continue to color his outlook and interactions with others.
2: Human Phoenix by Refusenik Refusenik's writing style immediately pulled me into Scott MacIntyre's world and made me want to keep reading. The way Refusenik introduced his main character to the readers grabbed me and gave the MC a vulnerability that was hard to ignore; you want to learn what happens in later chapters right away.
3: Island Mine by Refusenik The third of Refusenik's stories it showcases the effects of governmental greed and arrogance. The main character just wants to live his life, but extreme events keep getting in the way.
4: Unending Night by Jay Cantrell As with the other favorites listed here, I was attracted to this story right away by the strength (IMHO) of the characters. Jay has less time to present them in a single chapter but manages to do so that you get an understanding of who they are.
