Philosopher’s Crystal is about Philip and Julia. After the arrest of his parents, Philip is living alone when one evening he comes across Julia who is on the run. He offers her a place for the night—not knowing that his life is going to be turned upside down the next morning when a stranger knocks on his door and tells him to escape. Thus, Philip and Julia start their adventure, which includes traveling to the Roman empire, 17th century Amsterdam, and medieval Indian jungle. And the story has an unexpected twist, which made it all the more interesting.
The best part about this book is that many philosophical discussions are put in simple terms and written in conversational style. The base of the story is a bit weak, though. I definitely recommend this book if you like philosophy.
