I read Recalled to Life by Robert Silverberg while I was in
Spain (that blue sky). This is a science fiction novel about
a lab that discovers a way to bring people back to life who
have recently died. An ex-governor is hired to do the press
for the lab. It was clearly a clever philosophical novel,
about the reaction of the church and other groups to
this new procedure. There were number of loose ends like
a Senator who is accidently murdered. Still you have to admire
the book for dealing with the fear of death.
