A Home for Helena - The Lady P Chronicles, #2

After a woman with unusual psychic powers suggests that she has been misplaced in time, Helena Lloyd travels back two hundred years in an attempt to find out where she belongs. Widowed father James Walker has no intention of remarrying until he makes the acquaintance of his daughter's lovely governess. Lady Pendleton, a time-traveling lady herself, suspects that these two belong together. First, however, she must help Helena discover her true origins-and hopefully, a home where she belongs.
