I read it recently but it's disappeared from my list. It might have been Free.
It was about a lady who moved into a house with her partner. He ended up leaving.
The whole house was white (my dream) and nothing was out of place Ever it was part of the tenancy.
Things got weirder and she ended up having a baby with the landlord only to kill him I think.
It was like a b a Paris book or sims
