I have just finished two excellent books by Jennifer Chiaverini. "Mrs Lincoln's Dressmaker" (Elizabeth Keckley) and "Mrs. Lincoln's Rival". Historical Fiction. Excellent books. I listen to my books (audiobooks from the library). I am now on the fifth Walk book by Richard Paul Evans. This is the final book "Walk on Water" in the series. You have to start at the first book though - you'll lose the path of the story if you don't. This are my hot recommendations. Excellent to listen to while I am sewing. And yes, Jan Karon's books are excellent! An interesting bit here - Elizabeth Keckley sewed all of Mary Todd Lincoln's dresses while she was in the White House and the little bits and pieces leftover from the dresses Elizabeth Keckley kept and made a quilt. The quilt is now hanging at Kent State University and is beautiful. You can google Elizabeth Keckley and learn all about here. She also combed President Lincoln's hair for his going out in public. President Lincoln didn't know how to properly comb his hair and far be it from Mary Todd to help him! Learned an awful lot of history in those two books (the good stuff so to speak).
Good luck to your daughter. I am sure she will be fine! Have a good day. Edie
