And by best it could mean most compelling, or most artfully written, or most moving, or most funny, depending on how you'd define "best".
I've read 1 Marian Keyes and found it a bit too harsh / grim reality (does she fit the chic lit moniker?) for my taste, and I've read a Penny Vincenzi which was a huge rambling saga that worked through 6 generations of women - it was exhausting but not compelling enough for me. And I've seen the Bridget Jones films but not read the books. But that's it - so my knowledge is very limited.
I'd really like to know which writers other MNers would recommend?
