Brilliant and passionate, the 25 year old Leonardo da Vinci is an artist, inventor, swordsman, lover, dreamer and idealist. Gifted with visionary intellect and talents that are almost superhuman, Leonardo struggles to live within the confines of his own reality and time. When a chance meeting with a mysterious stranger throws his world into turmoil, he and his companions find themselves in the midst of a storm that has been brewing for centuries; a conflict of truth and lies, religion and reason, past and future. It seems only the shadowy cult of the Sons of Mithras and the power of the Vatican hold the key to the truth about Leonardo's past - and his future. A hero armed only with genius and invention, Leonardo must take up the fight against foes who use history to suppress the truth.
