I just finished Susan Fraser King's LADY MACBETH. Some of all-time favorites that I reread now and then include Mary Stewart's Crystal Cave series, anything by Sherri Tepper (the kind of SF that makes you THINK), C.J.Cherryh's FOREIGNER series, Evanovich's Stephanie Plum books when I feel the need to laugh out loud.
I am following this thread with interest -- always on the lookout for a new author!
