Mid-90s sci-fi book about a boy who somehow gets transported to another world

Question

It's about a boy who somehow gets transported to another world by a beam out of the sky. There were multiple beams, if I recall correctly.

I think I remember the beams being a timed occurrence, like every 7 or 10 years. And I think the book cover had a red background (like if it was dusk) and it showed multiple scattered blue beams coming out the sky.

He ends up living among a tribe; Native American or something along those lines. Marries a girl too. At the end someone in the tribe tells him of a way back to his home. I think they had found the same beams around the village.

That's as far as I can remember. I read it sometime in the 90's. I'm pretty sure it was young adult.

Answer 1

The Transall Saga by Gary Paulsen. The world he is transported to turns out to be a future Earth, decimated in the past by Ebola. This looks like the cover you mention.

He doesn't get told about the beam that returns him, it's a bolt of lightning.
