I might have got the wrong end of the stick and you have more than one dd, but isn't your dd in S2 whistlerx .
If she is not literate by now, then I agree, she has problems - and you are right to be complaining about the schooling. I could understand if you were encouraging a younger child to read more; when ds didn't "get" reading until he was 6.5 so for the following 2 or 3 years he was "between" groups and we had to supplement his reading encouraged by the school so he could - and did - get back into the top group).
I was a bookworm in my teenage (and pre-teenage) years don't read as often nowadays mostly because when I start a book I have to finish it in a single sitting
- loved Jane Austen, the Bronte sisters, Georgette Heyer, CS Lewis (not just the Narnia books), Tolkein..... Ds doesn't do as much "free" reading as I did - but even though he prefers sciences, he still has a good literacy grounding (and has just sat his English Higher where at worst he'll get a B).
The only "forcing" we, as his parents, have done is to make him continue English to Higher because, as my old English teacher used to say (and so did my mum, who was also a very good English teacher), "Whatever you do at Uni, even if it is science based, you will still need to write reports and construct a coherent argument".
In S2, he studied, amongst other texts, Kidnapped, a Shakespeare play (think it was "A Merchant of Venice" - he did "A Midsummer's Night Dream" in S1) and some poetry (including a bit of Beowulf) school supplied the books so I am not sure of all the texts he covered as he just got on with his homework and refused help from us
. I didn't feel the need to make him read extra. His creative writing and persuasive/discursive writing are both excellent, so I have no complaints. (I think it was at his S3 Parents Evening that his very intense English teacher said he'd written a very good creative essay and that he had discovered his "voice". To quote her, "I can teach him the correct grammar but he has to find his own voice" ,
