SOLVED. YA Fantasy trilogy - teen is transported to a parallel universe

[Sam]

I need help finding a series I read about 10 years ago. I’ve been trying to find it for the last 6 months and have now made it a mission to find the series.

This is what I think I remember:
The books were in a public library in the young adult fiction section. It was about a boy that was transported to a parallel universe. The parallel version of him was then transported to his world. I think it was a trilogy and one of the books had a purple-ish cover.

I honestly don’t know if I’m remembering this right or mixing with another series.
The parallel universe version of him was then transferred to his world, so they basically switched places. They ended up meeting each other/themselves at the very end. The other universe he was transported to had knights I think? It was a fantasy world and different from his.

I’ll update this as I remember more info! Really appreciate any help given and I can paypal whoever helps me find it $10
