The town of New Fiddleham has become aware of the shadowy creatures roaming its streets (and occasionally killing a citizen), and now the Mayor leads a political campaign to do away with them all. Unfortunately, this unrest means that the powerful Dire King (ruler of evil fairy) is making his final move and all that stands between him and the mortal world are the dedicated supernatural talents of detective R.F. Jackaby, his very able assistant Miss Rook, and their assorted human and non-human friends. Not everyone is up to full strength, though, and there is treachery afoot. The concluding volume in the Jackaby series is delightful and touching, from its intelligent humor to a final tribute to true love, with a few surprises concerning main characters thrown in for good measure. Warning: not everyone makes it out alive, but that doesn't mean they're lost forever. Ritter's Sherlockian tale concludes in a way that will satisfy readers, and will pick up a few new friends along the way who will want to read the quarter in its entirety.--Cindy Welch Copyright 2018 Booklist

A paranormal private investigator and his clever companion make a last stand against the forces of chaos in this fourth and final book. As an assistant to eccentric detective/seer R.F. Jackaby, Abigail Rook experiences magic, mysteries, and romance. A "lady of science and reason" who accepts the supernatural, Rook prizes her madcap American adventures over her comfortable yet confining British childhood, but she finds her new home threatened by war. As a wave of racist attacks turns their whimsical house at 926 Augur Ln. into a cryptozoological asylum, Jackaby, Rook, and resident ghost Jenny Cavanaugh take a new case and uncover a bigger conspiracy. Hunting mythical talismans, the trio discovers the veil between the mundane world and that of the Annwyn (fae) weakening and the Unseelie armies of the Dire King gathering. Jackaby is a delightful supernaturalist Sherlock, but Rook carries the story, narrating with dry wit, alliteration, and an appreciation for the absurd; faced with war, bureaucrats, and a diabolical life-sucking machine, Rook frets about a potential proposal from her Om Caini (lycanthropic) swain, Charlie. Ritter sets his story in a geographically nonspecific, slightly steampunk 1890s New England port city. It's helmed by a trio of white protagonists but offers a pointed and timely message about pluralism and the value of bridges over barriers. A humorous, energetic, action-packed, and magical conclusion. (Fantasy. 12-adult) Copyright Kirkus Reviews, used with permission.

Gr 7 Up-The fourth and final book in the series sees Abigail Rook, Jackaby's assistant, take the lead in this preternatural mystery. Previous familiarity with the characters is advised but is not necessary to follow the plot. In 19th-century New Fiddleham, New England, a mysterious threat from the ostensibly dead Dire King endangers everyone when the veil between this world and the fairy world, Annwyn, threatens to fall. Jackaby and Abigail are joined by a multitude of supernatural creatures, including Miss Rook's shape-shifter boyfriend Charlie and housemate/ghost Jenny who is working on her ability to become corporeal with somewhat mixed results. The group ventures between worlds trying to figure out if the Dire King has returned, or if someone has picked up his mantle. Mayor Spade has also declared war on supernatural creatures; no one is safe in this fast-paced tale. The main characters struggle in battle and with figuring out what their future holds, which leads to an unpredictable conclusion. Though the overall plot is a fairly straightforward whodunit mystery, twists and turns provide for action-packed pages. Events that have been heavily foreshadowed throughout will come to fruition in a satisfying ending that offers tantalizing hints of the characters' fortunes. This will most appeal to series fans and those who enjoy teen detective novels like A Study in Charlotte by Brittany Cavallaro or Maureen Johnson's The Name of the Star. VERDICT A strong purchase where the series is already popular.-Rebecca Greer, Hillsborough County Public Library Cooperative, FL © Copyright 2017.

In Ghostly Echoes, a new threat emerged for seer/sleuth R. F. Jackaby: the Dire King. Now, in this final book, the torn veil between the real world and the fairy world of Annwyn releases the Dire King's undead army to wreak havoc on Jackaby's nineteenth-century New England town. With wry humor, Jackaby's assistant, Abigail Rook, once again narrates this satisfying and surprise-filled supernatural mystery. (c) Copyright 2018.
