There are many books on UFOs and Aliens but most are in the air or over the land.
However, you might not be aware that there are also many UFO sightings underwater, or over water.
There are even some strong claims of UFO and/or Alien bases underwater.
Over 71% of the surface of the Earth is covered in water, much of which is in the Earth's Oceans. So it makes sense that Aliens visiting Earth would hide in the water or even build bases there.
Yes-there are reports from several places of possible Aliens bases beneath the waves. This would make a sensible place to hide if you have advanced technology which will allow you to hide underwater.
Some of the suspected underwater bases are near Malibu-California, Gulf Breeze-Florida, and the Solomon Islands in the South Pacific. There are probably a lot more submerged base locations we don't know about all over the world.
In this book I've provided as many Unidentified Submerged Object stories as I could research. I think you will find these stories to be very interesting.
