Is my mind playing tricks on me? I’m looking for a book I read as a teenager about two teenagers setting on a ‘quest’ to find a garden of eden? Or maybe they had the apple from the garden, and they had to save it? I believe it was set in Medieval Europe?

I'm sure I read this book when I was young. Unless I developed an advanced form of schizophrenia and I imagined the whole thing, as I vaguely remember the world and the characters;

• set in Europe, they travel across the continent to somewhere

• boy and girl, two teenagers, boy has a crush on her.

• some bad guys that chase them.

• Medieval europe, bows and swords were there.

• some magical apple? Or was it garden of eden?

Help!! I can't sleep.
