Between Heaven and Earth — Kay Brooks

Life can be very lonely when you have secrets. Oliver knows that better than most. Being over one hundred years old and still looking the same as he did back in 1834, most of his existence is spent moving from one place to the next in hope of hiding his immortality. Carrying the guilt of his father's death is exhausting and Oliver wishes for death to release him. Then, the wayward Tabitha enters his life, wanting him to take her on a journey through his history. In return, she'll teach him that love can conquer anything in its path.
