Portia De Costa - In too deep

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 tantalizing relationship with a man she's never met. Soon enough, erotic letters and toe-curlingly sensual emails don't suffice; she has to meet her mysterious correspondent in the flesh. (Part of the "Black Lace" series)
