Jennifer Chiaverini's new book comes out in February (the Union Quilters) I cannot wait! Her books are what inspired me to do more research on civil war quilts and history of quilts.
I also read and recommend anything by Francine Rivers and Karen Kingsbury. Debbie MacComber is good too. I like her Blossom Street series.
I read "the Constant Princess" by Phillipa George and was hooked on her Tudor Queen books.
