UPDATE the boy might have either been taken by or joined a military force when he leaves his village. during his time with this military force i believe he is captured and imprisoned.**
I believe the man might be able to read people's auras and this helps him seduce women as well as win all of the battles he has to fight in the arena against other humans with special power such as teleportation, pyrokenesis etc.
This story takes place in a world that has lost technology.
Update (Cover Art might have been a buff shirtless man) I vaguely remember trying to hide the cover from my wife because I was embarrassed of the cove art.
I listened to the audiobook roughly two years ago on youtube or hoopla.
I would say it was probably written between 2000 and 2019
The story starts off in a medieval type village.
The parts of the story I can remember are:
Towards the end of the story the man creates his own village with his children and they children create a fortress out of stones.
a boy finds out he has powers and is able to seduce the shopkeeper's wife in his village.
As he grows up, he eventually ends up being captured or something and forced to fight to the death against other beings with powers as a proxy for aliens, which I believe is found out later.
The next thing I can remember from the book is that the boy/man is saved by an alien in the woods who is a tree or something.
The boy also has a romantic interest in a girl from his original village, maybe she is married when he returns?
I can't remember if this was a trilogy or standalone novel.
Towards the end of the story I believe the man has children who also have special powers and fight off the aliens who had taken over Earth... maybe by causing a huge explosion or supervolcano or something.
There might also be a scene where he loses his virginity to the girl in his village, and afterwards she is raped or almost raped, and he maybe sends his dog to save her or something.
The alien creatures might have had humans fight as their champions because it was uncivilized or against the laws for the aliens to fight each other.
The humans who fought had different special abilities.
The main character might have had a slave woman or man take care of him while he was fighting in the arena. The slave woman or man might have been mute or a eunuch, I can't remember.
The aliens were earning the right to breed or evolve or something like that.
Edit: the boy/man might have also played the guitar
(This could have been a dystopian Earth the book takes place in.)
(It is not The Tripods or Childhood's End.)
I am going nuts not being able to remember the book's name!
