Secret Island by Christopher Hayes-BrownHardback
Christopher and David are two lecturers who have come to Egypt to visit the magnificent pyramids. But awaiting them are not the mysteries of Egypt but of a land altogether unknown. Beyond a shroud of mist and raging seas, guarded by ferocious creatures, Atlantis is as mercurial as it is eerily familiar. Its people are proud guardians of all life on earth, from the dinosaurs they have given refuge to, to the eagles they revere.
