Even after escaping the doomed Skomal, Marylou realizes that she is likely to die in the grip of cold, merciless ocean.  Her chances go from slim to none as she realizes her nightmare isn’t over yet… it has just begun. 

As the crippled Skomal is sinking to the bottom of the ocean, Marylou finds herself trapped between two malevolent and strange creatures.  But will she find an unlikely ally to assist her escape?

A sinister face appearing at over 5,000 meters below the surface of the ocean has Marylou fleeing for her life.  But where can you run when you are trapped below… Crush Depth?

After a startling discovery at her cabin porthole, Marylou determines to keep her from Tobias Havmann.  Her first solo exploration in a hard suit is another step toward fulfilling her life’s dream, but also brings her face to face with her worst nightmares.

Dr. Marylou Kelsum starts off on the voyage of a lifetime; a 14 month assignment exploring the ocean floor on a gigantic, state-of-the-art research submarine.  Her excitement about being on board the Skomal’s maiden voyage is tempered when she initial suspects and unwanted admirer.  But that is nothing compared to the horror that she uncovers shortly after they arrive at the bottom of the Atlantic Ocean.
