I bought this novel based on the strength of the other reviews on here and I'm pleased to say that they weren't wrong- as a first time Costa reader, I *loved* this and I'll certainly be dipping my toe into some of her other books ASAP.
As a long time reader of raunchy novels, I have to say that this is definitely one of the best I've came across so far. I couldn't put it down, though just a warning: this isn't the kind of thing you should be reading on public transport! The scenes are all set very well and there's something of a plot too- not just mindless sex, though the descriptions of *that* are admittedly riveting.
A brief summary: Librarian Gwen comes across as rather prim and proper on the outside, but when the anonymous 'Nemesis' starts leaving naughty notes for her in the suggestions box, a new side to her is unleashed. Accompanied by the sexy resident 'Professor Hottie' Gwen begins trying out the suggestions and enters a whole new level of fun, erotic excitement...
If you haven't tried erotic romance before and are wanting a full length novel to start off with then this is the book for you- but if you aren't sure if this will float your boat or not, then I'd recommend you try one of the Black Lace 'Quickies' books first, before moving onto something like this. It's bold, brashy and in your face, though admittedly will not be everyone's cup of tea!
