I have many favorites. This list is not all-inclusive.
Anne Rivers Siddons
(Who wrote the Shopaholic books?)
M. Medwed (What is her first name? Loved her latest, Elizabeth Barrett Browning...)
many, many children's authors...
...and Nicholas Evans. I just bought his newest, The Divide. Haunting. Powerful. Grabbed my heart and wouldn't let it go. It'll sit on the shelf next to The Horse Whisperer for rereading.
