This is a story where our hero is the heir to an ancient family legacy of pursuing immortality, where the most vile creatures in the universe are afraid of him because he thinks death sucks, and where the climax of the story is healing a cryogenically frozen person and bringing immortality to the masses.

It's not "easy to miss". The author beats you 'bout the head with his ideology. It's heavy-handed even for something explicitly didactic.
