Andrew Greig is the author of Mysteries of the Ancient World: The Secrets of Atlantis, which is a Kindle offering of a few dozen pages. Greig suggests that the Atlanteans were the descendants of extraterrestrials from Osiris, who became stranded on Earth. He claims that they eventually settled off the Atlantic coast of Morocco on an island that was destroyed by a meteorite! This book is full of inaccuracies as well as unsubstantiated speculation.
