Of my four Laser Books titles, this is the only one I wrote specifically
for that line. The book is very much a product of the mid-70s, when there
were meat shortages, gasoline shortages, and an apparent breaking down
of Western society's infrastructure. Nowadays you can think of it as being
set in an "alternate world" 1980s. This is a gloomy "if this
goes on" sort of book, but with a hopeful ending.
Caravan has recently been reissued, in both paperback and electronic
formats.
