I truly believe this series improves with each entry, though I highly recommend each of these books, which can also be read alone (though I am devouring the series in consecutive order).
GHOSTS OF OUR FATHERS includes the strong female character, Eliza, we met in A HAUNTING IN OREGON, plus her Oregon friend Claire. Now we meet Eliza's long-term friend, Daniel from Spokane, who is sort of a time wizard (no, not Dr. Who) and student of time. It seems that Steven and Roy's paranormal lineage, which commenced with Roy's grandfather, is now bleeding danger into the present from an act of preservation Roy's father, as a child, achieved eighty years in the past. It's a ver complex scenario, but Mr. Richan performs it masterfully and kept me riveted throughout.
