HI - I remember a story I read re a young couple (I think) who found a portal on their fathers farm, and was transported to another world/planet where they became royalty I think - A fairly long story - father was aware and I remember a chest full of books being found. Any help would be appreciated
Your decription has similarities with Wizard's Legacy by Rotedrachen which was recently mentioned in these forums. It isn't an exact match.
'Wizard's Legacy' by Rotedrachen sounds close to your description.

O wow - Just had a look and I think this is it - I cannot believe someone else was looking for it so recently. Thank you
