Gordon Rupert Dickson was an American science fiction author. He was born in Canada, then moved to Minneapolis, Minnesota as a teenager. He is probably most famous for his Childe Cycle and the Dragon Knight series. He won three Hugo awards and one Nebula award.
A pretty good trilogy, short and full of thrills and adventure. It's actually more of a 3.5 star for the typos of the Kindle version, it was worse than I thought, but I was still able to read it and enjoy it. Very imaginative, and it does kinda make me think it's like a mix of Tom Swift and Treasure Island. Definitely worth a re-read.
Probably a good read for 9-14 year olds. Lots of philosophizing about life and proper actions, morals, etc. The protagonists are either squeaky clean or evil. Overall rather juvenile in it's writing. I actually only made it thru 2 1/2 of the 3 stories - I just couldn't take any more, had lots of other stuff to read & wasn't getting much from these stories.
