I love to read, so i also am interested in the book you picked up but didn't read.
JD Robb's In Death series is WONDERFUL, I love love love love it, BUT there are LOTS of swear words in there and some pretty kinky steamy sex stuff. I actually wouldn't recommend it to you. I was surprised to see people list it.
Lauren Willig has a series. It starts with 'The pink carnation", the Black Tulip, The silver Orchid etc. If you have ever read or seen the Scarlet Pimpernell it's that time period, the 1800's?? in England and France with Bonapart and the guilletines etc. The Pink Carnation is a female Spy, and i just love the characters in it. Some of them make me laugh outloud, lots of sweet love triangles. and generally a happy ending. There is a bit of switching from past to present day,which is a nice change too. No swearing unless the occasional bugger, said in an english accent, whIch i can forgive them for because they are so darn cute and bumbling.
So for you my friend, we have mystery and intrige, romance and comedy, they make me feel good. I don't have to think too hard, just an escape, but well written.
oh i think the real title is The secret historyof the pink carnation
lauren willig is the author I think someone else mentioned Joining Good reads.com its' great for reading reviews and keeping track of what you've read.
