Icebound is one of Dean Koontz's earlier works, revised
to bring it up to date. It's original title was Prison
of Ice.  Like most of his other works, Icebound's story
takes place over a short time:  

Set in the near future, a group of scientists tries a
daring experiment north of the Artic Circle: Set off a
series of high explosives on the edge of an ice field,
and make an iceberg that can be towed south to provide
clean water for irrigation.  All goes well until an
undersea earthquake breaks off the ice they're working
on, trapping them on a floating bomb, which will deto-
nate in a handful of hours.  Toss in a raging blizzard, 
dwindling fuel for heat, and the discovery that one of 
their members is a murderous psychopath, and suddenly 
their future doesn't look so bright.

Fast-paced and engaging, this is a bit of a departure
for Dean. The style is more like that of Alistair Mac-
Lean, with less of the character development fans of 
DK may be used to, but all of the action we've come to 
expect.

OR THIS ONE

A widespread drought is causing murderous famine. There
is one possible solution: giant masses of Arctic ice, 
split from the polar pack by high explosives, could be 
moved to parched coastlines and melted for water.

In an arctic icefield, a special team of eight scientists 
has planted sixty powerful bombs that will detonate 
automatically at midnight. But before they can withdraw 
to the safety of their base camp -Edgeway Station- a 
shattering tidal wave breaks loose the ice on which they 
are working. Now they are hopelessly marooned on an 
iceberg during the worst winter storm of the decade. The 
bombs in the ice beneath them are buried irretrievably 
deep...and ticking.

Abruptly thrown into a desperate struggle for survival, 
the Edgeway scientists are further plagued by the 
discovery that one of them is a ruthless killer hellbent 
on a strange mission of his own...
