The Nucle Trilogy

The Nucle Trilogy - The Complete Edition, which comprises all three books of The Nucle Saga (I, II, and III) will transport you to The Nucleverse.
The Gladanian twins Zindor and Rador from the recently invaded Kingdom of Gladus are introduced to Commander Eroberer, a leader of the resistance movement, as an Emperor spreads his Empire against local kingdoms.
The invasion of their house by this neighbouring Empire completely shakes up the brothers' world. The brothers vow to fight back in the midst of the mayhem and destruction, but they have no idea that they will be exposed to a potent mythology that has been kept secret for years.
