I have read the books previous to The Man Who Made Husbands Jealous and found that this fitted in nicely with those. I didnt, however, surpass them in anyway at all. In Riders you loathe Rupert and the way he treats people but by the time you have finished Rivals you realise how great he is; in Polo you just love him more. There are so many characters in the previous three that you really like or dislike so much that they make a huge impact all the way through the novels... Rupert for being so hideous in the first but changing, Taggie who is utterly lovable and Helen who is totally irritating all the way through; but I didnt feel that way about any characters in the book there wasnt anyone that made a huge impact on me in the way the previous books had. I found Lysander quite irritating at times, he really annoying in the way he falls in love three time in the space of a about 600 pages, Kitty is so wet.... you just want to scream LEAVE HIM!! the whole time, and the rest of the cast are so concerend with their looks is ridiculous, i dont think there is one normal sized, normal looking person in the whole of Paradise!
Jilly Cooper's novels are absolutly absorbing, all of them are (i have read Appassionata and am half way through Score! at the moment), but I do find with TMWMHJ that it is too flitty and the story is not a patch on the rest. i do recommend it though as it fits very well with the rest of the novels. It is best to read them in order though as you get to know the characters quite well and when there names are dropped in the next book you find yourself smiling at them getting on so well.
Keep up the good work Jilly, your novels have kept me entertained for weeks now. They are so great you find yourself constantly saying 'Just one more chapter and the lights definatly going off!!'
