It's hard to say if anyone could have foreseen what "The Quilter's Apprentice," the debut novel by Madison author Jennifer Chiaverini has wrought. That 200-ish-page book was the first in what is now a series of Elm Creek Quilts novels that runs 19 bestselling books long. Her first non-series book, "Mrs. Lincoln's Dressmaker" - based on the life of Mary Todd Lincoln's seamstress and confidante Elizabeth Keckley, who was a former slave - is due out on Jan. 15.
