Yesterday's Dreams, Book Three in O'Brien's series called A Slip in Time, continues with our favorite characters, Francine, Luke, Dora, and Wade. The two sisters each love a Grainger brother, but one love has been fulfilled, while the other love is torn apart by two different centuries. Fran and Luke begin to make a wonderful life for themselves while living in her family's cottage. Many ups and downs keep this couple close to our hearts, as they struggle with decisions that will affect their future, with fear of being discovered, and with illness that threatens the loss of life. Dora has returned to her own century with a broken heart. She leaves the love of her life behind to sort out his problems with his family. Knowing she can never go back again, she tries to forge a new life while still keeping in touch with her sister in the 1880s through messages left in the trunk. As time passes we see Dora struggle to forget Wade, but illusive dreams continue to visit her in the night, tempting her to return to a crooked smile and loving arms.
