G.I. JOE: Adventure Team 3: The Devil's Triangle (Kindle Worlds)

The Bermuda Triangle has been called a hoax, a myth, a ghost story to be told to the gullible and the superstitious. It's said that all the disappearances of ships, planes and people in the Triangle are coincidental, or easily explained. The Bermuda Triangle is a harmless track of sea in the Atlantic Ocean.
You would be a fool to believe that.
Jake and his friends learn first-hand about the dark and mysterious forces that call the Triangle their home.

Things are no better back at the AT Base. The Quartermaster is concerned about the reasons behind the Adventure Team's swelling ranks, due to the nightly-openings of the Tomb of the Fallen. Also of concern is their missing Commander and teammates, the arrival of the Atomic Man, and the increasing interference of Captain Abernathy and his quest to turn the AT into his own personal fighting force.

And in 2016, Jake's nine year-old daughter is still searching for her father, and trying to stay clear of the callous and cold-blooded woman that claims to be her mother. The woman, who calls herself Madelyn Blais, is also searching for Jake... but with a more sinister reason in mind.
