You really need to know about this question
on this forum.
Someone else is searching for the same thing, and it is very obvious from the
very detailed description.
There are two answers with some links, and a slew of comments with more links.
It isn't found yet, but several others know about the same book and have searched for it too.
I say it isn't "found" even though an answer was "accepted", because the OP planned to use the links for a "research vector". I did the same, but the book isn't found yet.
There are lists of SRA Reading Mastery books
like this one.
If you know what to look for like I didn't, Bookfinder shows results that also give you the ISBN, making it easy to find without title ambiguity. Like
this level 5 book.
Internet Archive has some volumes online, like
this Reading Mastery Level 6.
I searched writing "archive" and SRA "Reading Mastery" and found some of these. But I wasn't familiar with them so just searched the higher "levels' as they call them, to get past the primary readers. They have some good stories and poems. I did scan a few Archive books and didn't see any story like that. You can even use the "search inside" function on the site.
It's unmistakable that other people would love to read it.
I was unfamiliar with it and went on a steep learning curve, but it would be great for someone with a memory of the actual Levels and Volumes and titles to zoom in on it.
