To be quite honest, that first letter had me second guessing about reading the rest of the story. Good thing I stuck through because, wow! What a lovely piece this is!

I adore the way you transitioned Wendy's way of putting thoughts into words as she grew up. You could clearly see how much Wendy has grown.

The part where she talks about finding the letters by the window just broke my heart. Also reminiscing about the time where Wendy tells Peter had a funny address was a nice touch.
Aah, I wouldn't mind if you didn't write a reply version to this story. I think, not knowing what Peter would've said would make this piece even more beautiful.

Hey, I'm doing this new thing where I review every story that I read and leave a proper, honest review, not just three words. If I offend, I'm really sorry I never mean to. So lets get honest aye
I liked it. A lot of people do fanfics with letters and you just don't get the right personal emotion through that a handwritten letter would contain and you captured all that personal stuff perfectly.

I loved the transition with writing style to show her age and her growing maturity.
When Wendy called him "Mr Pan" I just felt like there was such a loss of faith in her previous hero.

The only thing is, I wouldn't really call this story "angsty" to be honest. I don't think the emotion is...quite raw enough (if that's the right phrase).

It doesn't seem to attack the readers heart with pain and the whole "argh" factor which I think most angst stories should do.(But saying that, that's just my definition of angst).

And also, I know its hard on fanfiction with the setting out, fanfic often deletes triple spacing, like for instance to break up letters. But I think it would be easier to read your piece if the different letters were broken up some other way, hyphens or some other kind of break?

All in all, I liked it)and especially loved the almost final lines of"In case there is a chance that strange old hopeful ladies can fly too. I'll always believe in you Peter Pan.
A beautiful ending)

This story was sad but I liked it. Keep up the nice work.

Too awkward to be poetry, and too fragmented to be prose, but an absolutely beautiful hybrid of both!"Letters" made me cry. I love how you transitioned the tone of the letters to correspond to Wendy's growth without explicitly stating it. That takes skills.
I think the last letter was the most beautiful of all.
Do you think you could add one more chapter telling what Peter's reactions to the letters were? Pretty please?
