Great expectations / Charles Dickens ; retold by Clare West. (OCLC #182520269)

We recently got a collection of simplified editions of classic works. For example, where the original says:

My father’s family name being Pirrip, and my Christian name Philip, my infant tongue could make of both names nothing longer or more explicit than Pip. So, I called myself Pip, and came to be called Pip.

This version says:

My first name was Philip, but when I was a small child I could only manage to say Pip. So Pip was what everybody called me.

I wondered, is this a new expression of the work “Great Expectations” created by Charles Dickens? (maybe an adaptation or free translation?) or is it a whole new work? Who should be recorded as the creator?

RDA 19.2.1.3 includes as an example this very situation (and this very title, but with a different reteller):

Great expectations / Charles Dickens ; retold by Florence Bell

and indicates that “Florence Bell” should be recorded as the creator of the (new) work.
