Reunion of Worlds

What if the pevensie's had been older in Prince Caspian? What if Caspian had fallen for Lucy, instead of Susan? The pevensie's are back in England now, and a school trip there going on might just take longer than they think. And what happens when something unexpected happens while on their journey?

I really suck at descriptions, I'm sorry.

I don't own the Chronicles of Narnia, I'm not that good.
I only own the plot and a few characters I made up.

Also this is my first story, so if you have any tips, please let me know!?
