Had to order this in paperback as I couldn't find an ebook on Amazon or anywhere else. I enjoyed reading this a lot. Wouldn't really call this the 2nd book of a series since it worked perfectly as a stand-alone.
It's a future where clones are being made for specific purposes - 'toolmen'. They're pretty much slaves to uncloned human beings, have to obey whoever they're assigned to, and they have built in biological clocks that kill them off around 40 or so. Alex is a toolman, made to be sort of a diplomatic aide and liaison, and he's just about to 'flare' and die. The book starts with Alex and his scheme to avert premature death, and moves on to another clone, August. August is a younger clone, genetically identical to Alex, and people keep crediting him with Alex's virtues and faults. This is a very well written future dystopia story. Not really a romance although Alex has an MF relationship and August an MM one. There's real violence and death and some of the violence is horrific, especially the episode where August is kidnapped and what he does to himself to thwart the kidnapper's intentions, but this is also a hopeful book with a very hopeful ending.
