Second trilogy consisted of the 12th book The Cursed, 13th book the Hexed and 14th book The Betrayed.

First trilogy consisted of the ninth book The Night is Watching the tenth book The Night is Alive the eleventh book The Night is Forever. Although not mentioned exclusively, I consider them as a trilogy as the characters kind of flow from one book to the next keeping the continuity. This forms the third book in the third trilogy within the series - first book being the 15th book The Silenced and 16th book The Forgotten. The plot is set in Colorado and occurs right after the events in The Forgotten. The plot centers around FBI Special Agent Diego McCullough - newly recruited agent to the Krewe of Hunters - and Scarlet Barlow - a historian working at Estes Park, Colorado. The Hidden is the seventeenth book in the Krewe of Hunters series by Heather Graham and published in September of 2015. Recommendation: Yes, pick it up for a mystery involving paranormal elements, historical flair and the romantic side of the plot. Diego heads to Estes Park, determined to solve the bizarre case that threatens Scarlet's life-and to reunite with the woman he never stopped loving.For review of all books in this series: Go here Then the museum's statues of historic people, including Nathan Kendall, begin to talk to her, and she knows it's time to call her ex-husband. When Scarlet unwittingly takes pictures of people who've been murdered-just like the Kendalls a hundred and fifty years before-the police look at her with suspicion. Diego-who's just been asked to join the Krewe of Hunters, a unit dealing with 'unusual' situations. She recently came to Colorado, reeling after her divorce from FBI agent Diego McCullough. Now historian Scarlet Barlow is working at a small museum attached to a B and B, the same building where that murder occurred. Shortly after the Civil War, Nathan Kendall and his wife were murdered there, leaving behind a young son. The newest entry in Heather Graham's popular Krewe of Hunters series, The Hidden, is a page-turner-a story that brings past and present together in a completely unexpected way! Can the same killer strike again-a hundred and fifty years later? Estes Park, Colorado, is a place of serenity.
