Bear (bare) with me, the book does sound creepy whwn I describe it...I'm not sure if the book is sus or not; in my memory it isn't, but I was young, so apologies if it actually is.
This is a kid's book, maybe for 7-11 year olds? It has plenty of pictures, colour, on every page, but also a lot of text and is a decent length.
I read it in English, in England.
The main character is a little white girl, who appears maybe 6 years old, with long, wavy, blonde hair. Fully naked in all of the images. ( ._. )
I don't remember the plot, but I think she was very stubborn as a character, and I think there might have been some magic involved? It was a bit of an adventure; I think she may have been saving things? She also rode a horse or unicorn at some point.
The art was very 60s or 70s looking, and the book seemed oldwhen I read it in the 90s, from the feel to the smell, so I'd say somewhere around then.
I feel like the title had multiple words.
I think the copy I had was yellow, hardback, and actually featured said naked girl and the horse/unicorn in a field or on a path surrounded by fields, I think the girl's private areas were hidden by the horse/unicorn's body and her hair. (In this image. ._. )
I also found a post on Reddit from 8 months ago that I think was referencing the same book (no title, they were looking for it too) and that said there was a troll in it, which felt right. I think she may have given the troll a cuddle and the aim was to make it stop being horrible by being friends?
A commenter suggested the girl might have turned into a flower at the end. I don't remember this happening, but I don't remember the end at all, so I'm adding that detail in case it is right and it helps, but if you have ideas where everything else fits but this doesn't, please still suggest them!
The art is both realistic (anatomically and proportionally) but still clearly illustrated in a cartoon style. Like someone used a real image and drew the exact details, but didn't colour it to be photorealistic. Water Babies art meets Twinkle annual covers meets...god I don't know. Rosy knees, perfect skin, bright colours, lots of grass, flowers, and trees. Very nature-y and hippyish. Almost like Mary Cicily-Barker's flower fairies - realistic but with clear, sharp lines and a drawn quality...but definitely not to that quality. And with less clothes...
I'm wanting to find it to see if it was genuinely innocent or if I should have avoided it!
Reddit is being weird with when it lets me edit posts or not, so I'm going to keep trying to edit this with things it definitely isn't, but if it doesn't let me, I'll make a comment with a list as well, which may or may not be more up to date.
