Another early Koontz book now slightly revised and released in his own name. An expedition to relieve a worldwide drought by blasting icebergs free from the Arctic Circle is stranded aboard a time bomb when a freak wave cracks a portion of ice, containing sixty bombs, free to drift. If such a problem weren't enough it appears that one of the group is also a murderer! There seems no hope of rescue until suddenly a Russian submarine on manoevres nearby comes to their aid. The only problem is time - will they be rescued before the bombs detonate? A great novel yet again. Although lacking the great depth of characterisation of his later books (mentioned in his own Afterword) this still gripped me and I finished it in a matter of two or three days.
