So, here's my list of recommended josei:
1.) Talking about - really enjoyable.
2.) The Other Side of the Mirror - it was a little short, but the art was great. And the oneshot 99 roses from the first volume was excellent!
3.) Blanc Marie - really funny josei oneshot
4.) A Funeral Procession of K - different and addictive! It talks about one's obsession for love.
5.) Dokuhime - It's still ongoing, but the story looks really promising. a little dark
6.) Ikenai Candy Love - a very funny and entertaining oneshot.
7.) Helter Skelter - the lines between sadness and happiness, between sanity and madness, between love and obsession are so thin. This manga will show you that.
1.) The Boy From the Moon - it's a shame it was dropped by the author, but even that one volume makes it worth it.
2.) Do-Re-Mi-Fa-Sol-La-Si-Do - another grate title put on hiatus by the manhwaka [I'm so unlucky when picking them *wahhhh*]
All works from Fujiwara Kaoru [she's my favorite josei artist]:
~ Vampire Girl
~ Mukashi no Hanashi
All her stories are original, have a touch of madness and the art is gorgeous. I say you should give them a try.
As a beginning you could start with the josei Storm in Heaven offers: http://www.storminheaven.org/gsearch.php?g=josei [they are short, HQ and gorgeous]. I haven't read them all, but from what I did, I loved.
