"The small-scale focus works extremely well. What we get - rather than a big diorama - is a stripped-down, personal look at how these peoples' lives have been affected by the Kéthani and their ability to grant immortality. The stories are by turns sad, uplifting and extremely thought-provoking. Brown raises a number of philosophical questions: what role does God play in all this? What are the implications of not having the implant operation? Is the prospect of eternal life really as good as it seems? If you personally are against the implantation process (as many humans are), should you refuse to let your child be implanted? Is life suddenly made worthless by the fact that death is no longer something to be feared?"
