W.I.T.C.H. Stone falcon.

"Something strange is happening to Tarani. She is followed everywhere by Mongo, the new boyfriend from her senior class. Who is he and what terrible secret does he know, if it is easier for Tarani to face the Time Ghost Gorgon than with him? In this book, sorceress friends from the W.I.T.C.H. go on a second journey through time. They must find the next piece of the Shattered Orb, the Eagle Fragment, before the Gorgon. This time they find themselves in the distant past of the world of Orbis. In this world, all issues are resolved with the help of brute force. Will the sorceress friends be able to prove to the locals that friendship, love and mutual understanding are much more important than strength? Can they outrun Gorgon in search of the Fragment?"
