Liked this a lot, a nice twist on the usual time/personality transfer tale.
A little too much car techno-babble for me, but really well done overall.
If I had a complaint, it would be that I felt I'd missed some chapters between chapter 23 and the epilogue.
I'd have liked to see more of how he managed to integrate into her new life.

Anyway, a good story, would recommend it.

can't wait for the rest of the story...

Wow! what can I say? Laughed out loud at this one, it's just terrific!

You have certainly doen your homework with this story, I lived it, and I can't find much wrong with anything, I am certainly looking forward to more chapters

Being 63 I can identify with Bert and the age period (I graduated fron HS in 1969) this is an incredible story, I'm always interested in time travel stories and this one looks lik it will end up on my favorites list glad you came by to check out my story (Wishing On a Star) I saw this story on your profile decieded to check it out damn glad I did!

[Lowell mill girl] I think this whole name is one big proper noun, so Mill Girl should be capitalized as well

[adjust the punctuation',] I'm not sure if this is meant to be intentional or not, as you are talking about punctuation here. But if this isn't supposed to be an inside joke, then the comma should be inside the single apostrophe quotation mark

[I thought to myself as I cut and paste] tense: as you're writing in the past, I think this should be "pasted"

[now I knew why women needed toilet paper when they pee] This line made me laugh out loud

[black is fine." I responded] speaker tag should be {black is fine," I responded}

1962, huh? That explains the JFK, Jackie O cover. I really like the concept of time travel plus gender switching—there's so much potential in that that you could exploit.

I'm getting a sense of stream of consciousness from the narration of this piece. There were definitely a couple of moments where I could feel the narrator's sense of being overwhelmed—like when he found out he's turned into a girl—in the prose.

Stylistically, two things that bothered me were the ellipses the 'thoughts.' The ellipses were really hard on the eyes, and while I know there are naturally places in the prose that need a pause, I can't see why a comma or period wouldn't do the trick. Also I just didn't understand why the narrator needs to have internal thoughts when he's narrating the story. For example:
['Three kids, three caesareans,' she didn't look bad at all] What makes the first part a thought and the second not a thought?

Jim-Bert actually sounds a lot like a teenage girl when he talks to his parents. Maybe that' because he is bewildered and ignorant of what just happened, as teenagers almost constantly are. Maybe it's just me, but I did find it a little difficult to believe when he's running through all the sci-fi time travel stories he knows, because I'd think waking up finding out you've become the opposite gender (a completely new experience, as opposed time travel, which is just going back to a time/place you've already experienced) would elicit a much stronger reaction.

A very interesting take on the 'live your life again' theme. I am engrossed, and eagerly waiting for the next chapter.

It seems like a story that could sell well as teen sfi-fi if developed with care:)

My reading experience with this is that you can tell a good story, and you're technically tight, but at this point I'm really wishing there was some kind of conflict.

Awkwardness abound!

You have a natural writing style and seem like you have a passion for telling this story. I don't think that most of the POV from Mark is necessary, though, because it seems redundant. The reader can guess Mark's reactions and thoughts from Bert's descriptions.

Cliffhanger! Eep!

I ship Mark/Bert now :P

The plot thickens!

Hi:

Read through it. At first I was very engaged. The most interesting points are about the switch, the emotions of the new Bert dealing with seeing her parents, and then the conflict between the new Bert and her parents, with the restrictions and friction that would be caused by a full-grown man trapped as a child in the 60's. This was further increased by his concern over the loved ones left in his past life.

But Chapters 3 and 4 seemed to drag for me, perhaps because the story focused more on the smaller details of the protagonist dealing with his new body and environment.

I was also wondering how the time travel happened, since the protag was not involved with any time travel test or experiment, etc. This definitely feels more like a fantasy than sci-fi.

James has had what no man has had before!
