The Spark of Life — Hayford Peirce

Erika, his daredevil girlfriend, is being held by a cult of religious fanatics who deem her the essential element in their breeding program to recreate the genuine, living Noah. . . .

The cult's murderous leader, the Venerable Shem, has just missed killing Larry four times. . . .

So now he's catching his breath in a stolen submarine under a thousand feet of icy Canadian lake water when things do get worse -- much worse:

Three alien monsters knock on the submarine's hatch: the Egg, the Floater, and the Invisible Man.

They've come to Earth to find a 65-million-year-old treasure, The Spark of Life.

But, as they discover, The Spark of Life is precisely what the Venerable Shem is determined to find first -- at any price.

Including their lives.
