41.13: Locke and Key (Volume 5): Clockworks, by Joe Hill (author) and Gabriel Rodriguez (artist) (2012 Trade hardcover, issues 1-6)

This is one of the most unsettling comics I read. The Walking Dead has zombies and The House of Mystery has surreal and dangerous characters, but the seemingly normal backdrop on which the magical premise of this series--a Keyhouse, with keys that unlock magical powers only for for children--is set, can prove both comforting and disturbing. Volume 5 takes readers further into the world accessible through the keys, as the Locke children confront their nemesis by venturing into the past with the Timeshift Key. This key allows them to see the history of the keys, including the role they played in their  father (deceased) and uncle's lives. Since all memory of such magic is erased once children leave the house and enter adulthood, these stories have been lost between generations, and Tyler and Kinsey's knowledge of their past use may offer the best hope for their own futures, and that of their little brother Bode.

When I picked up this trade, the clerk at the comic shop said something about the end of the series. I truly hope he was mistaken--or that we have at least one more story arc to come--as it's hard to imagine this world concluding at this point of the narrative. Stay tuned...
