I read a lot of other stuff as well, but SK sets the bar high - I nitpick other authors based on his perfection. I like Steinbeck (Cannery Row stuff mostly), McMurtry (his character development is intense, like SK), Koontz (sometimes, he scares me though), Marian Keyes (laugh out loud funny) and Fannie Flagg (ditto on the characters).
Holly, if you like Marian Keyes, you'd also like Claudia Carroll. A friend from Ireland started me on her books & she's so funny! I much prefer Brit & Irish 'chick lit' to American--less breathless gasping over impossible physical perfection & more humor, family, and realistic lives
