Children to tween book- Girl moves in with aunt and travels back in time to the same manor and meets her doppelgänger

[Lena]

So I’m actually not sure whether or not this is a book or something that my brain has made up but i read this (maybe) in 2018-2020 and it’s just been on my mind. A girl moves to live with her aunt after the death of her mum and when she falls asleep she travels back in time to her aunties house as a maid. There a girl lives as the lady of the house but is trapped there and is not aloud to leave. They meet and decide that the girl from the future will stay and pretend to be her whilst the lady of the house will run away either the stable boy that she fell in love with. One scene i remember is that she was cleaning and an arrogant server came up to her and shoved her so she poured a used chamber pot over his head ( don’t ask why i remember that :) but yeah thats it. Like i said it may be my imagination but I’m not sure. It had a drawn cover

Hi Lena,

Set in an English manor, or somewhere in the USA, for example? Assuming you can remember?
