In a post-apocalyptic Earth devastated by a small number of people in order for them to gain immortality, a few clusters of survivors live in new cities built from the ruins of the old areas.  They are trying to restore some kind of order, fighting against weird zombie-like creatures and attempting to avoid the 'Strangers', those now-immortal humans.

Simon Japp is an unusual man: he survived for over fifty years without aging when the earth-shattering events took place. Now he is attempting to survive and come to terms with his violent past. He keeps himself aloof from those with whom he interacts, but something about beautiful computer geek Sage Corrigan gets through to him.

Sage knows that her friend Theo is in love with her. Perhaps she should feel something for him, but she doesn't. Simon, on the other hand, is strangely fascinating. When Sage goes undercover to the polygamous bab-breeding colony from which she escaped, she needs a husband - and Simon ends up going with her. Can they play at being husband and wife without feeling more? Can they find the mysterious 'Remington Truth,' the man who may be partly responsible for events?

This fascinating story isn't at all predictable. Sage and Simon have their secrets, and the reader is often unsure as to what's going on. The setting is well-written with the dark, dreary, scary life that the survivors lead well-drawn. All in all, it's a good, attention-keeping story the whole way through.
