Prince of Sunset by Steve White
This is a tale of undying friendship and the impact true friends can have on the fate of the known universe.
Basil Castellan is followed throughout the book as the main protagonist. Basil is an idealistic supporter of a failing Imperial system. As a teen, he has a startling encounter with a mythical being that, unknown to him, will be carried with him the rest of his natural life.
As often seen in military science fiction, there is exemplary loyalty among friends. This loyalty includes camaraderie, trust and sometimes even love.
White does a nice job crafting likeable characters. He could have made a multi-book series out of this but chose to limit it to one book that cries out for a sequel.
I enjoyed the book and I recommend the book.
