This book is the classic sequel to the first book in the series - "The Cave of Time". The reader revisits the cave of time but this time through a different entrance.The reader, inside the cave, meets a old and mysterious man who helps the reader to time travel. This time even more dangerous and fascinating adventure awaits the reader. A must-read from me!
