I love that line about Eustace Clarence Scrubb too. Narnia also throws up, in a description of Cair Paravel: "and oh, the cry of the seagulls! Have you heard it? Do you remember?"
In Guards! Guards!" by Terry Pratchett
after the early paragraph in which Vimes is musing
the city wasa, wasa, wasa wossname. Thing. Woman. Thass what it was...Strung you along, let you fall in thingy, love, with her, then kicked you inna, inna, thingy...and just when you thought you'd got her, it, out of your, your, whatever, then she opened her great booming rotten heart to you, caught you off bal... Only thing you were sure of, you couldn't let her go...
Then at the end we get his sudden realisation that Lady Sybil is trying to catch him, and his thoughts are
...and she had opened her heart, and if you let her she could engulf you; the woman was a city.
