In Too Deep by Portia da Costa

9780352341976 Black Lace
Lust among the stacks...Librarian Gwendolyne Price starts finding indecent proposals and sexy stories in her suggestion box. Shocked that they seem to be tailored specifically to her own deepest sexual fantasies, she begins a tantalising relationship with a man she's never met. But pretty soon, erotic letters and toe-curlingly sensual emails just aren't enough.

She has to meet her mysterious correspondent in the flesh.
