Two books combined - The Wizard of Linn

Taking place ~12,000 A.D. our time (the "golden age"), the Empire of Linn is a Dynasty. The daughterinlaw of the Leader gives birth to a "mutant." His mother has somehow been exposed to radiation while pregnant with him. The usual would be to kill it, but it's decided to let it live. Nothing is wrong with the child's mind, but its body is defective.
This boy is taken under the wing of the "atomic scientist" Joquin, who spares none of the grandfather's money in hiring tutors to teach him.
Atomic scientists are those who study and guard the remnants of the golden age, whose power mankind had used to destroy (our) civilization. They believe that the radiating materials are gods. They, the atomic scientists, are revered and sometimes protected.
Clane grows up to be a good-hearted genius, and because of political maneuverings on the part of his grandparents (who constantly intrigue with each other) he is made Chief Scientist at the age of 16. This is the beginning of his rise to power over the Solar System.
Curiously, the Empire has spaceships and spacescooters, but when the Linn dynasty is in battle against Venusians or Martians or Europans, they shoot arrows out of the spaceships ( )

dry & I didn’t understand the ending ( )

Troppo corto per potersi esprimere al meglio.
La storia è narrata in maniera piacevole e veloce; a volte troppo veloce; risultando quindi superficiale. ( )
