Excellent. Good characters, good storyline, good science fiction elements.

Joe is on a routine mission to pick up from the ocean trench what the mining robot has harvested. He's just on his way back when he's attacked by some gigantic sea creature.

Peter gets back from a test run of the top secret one man sub, about the same time Joe is rescued. Judith says it better be something good when she receives a call interupting her vacation.

Meanwhile 17 year old Andie Lipscomb is on a plane heading for what she thinks will be her Florida beach vacation with Uncle Peter and Aunt Judy. Well, not quite, it's the reseach station 90 miles off the Florida coast. At least Andie handles the plane ride better than the vixen reporter.

When everyone gets together to decide what to do about the creature, a new thermal vent, with it's potential new profitable lifeforms, is seismically detected.

They can't really ask for a sub to check out the creature -- too many people would think it a hoax -- but the vent allows them to get the sub and they can swing by on their way...

It was a great story whether you got your vicarious thrills putting yourself in the position of Andie, Peter or Judy.
