Query: Intriguing Fantasy Book

I read this book and was intrigued by the imagination of the author. It is a short book, ideal for the young reader yet it is filled with adventure. It is the story of a man who searches for the plant of life in the Garden of Eden. He finds it, cultivates it, and then is murdered by his own son. The plant makes people invincible and so he builds an army of invincible soldiers to take over the world. You will have to read the book to find out what happens next. It is definitely a "must read"!
