Ongoing Series?

Does anyone have any horror series they’re engrossed in and eagerly awaiting the release of next book? My wife was so excited about Onyx Storm and I was kinda jealous cause I’m always waiting on standalone books (with the exception of The Indian Lake Trilogy). Would love to pick something up - preferably something that will have a sequel; in my fantasy reading life I am still waiting on Winds of Winter and book 3 of The Kingkiller Chronicles
