Frances Hardinge is a damn good storyteller (and Emilia Fox is a top notch narrator)! Yes, there are gothic shenanigans involving an eldritch tree that thrives on lies and produces psychotropic truth-fruits. Then there is a suspicious death to be investigated. But *really* it is about scientifically-minded Faith refusing to content herself with the crumbs that fall from the table as she grows towards womanhood in the Victorian era.
