Book suggestions: Station Eleven by Emily St. John Mandel, The Last Policeman by Ben Winters, The Parable of the Sower by Octavia Butler, The House with the Clock in Its Walls by John Bellairs. The list for this square: Doomsday.
New release: mystery, suspense, horror or supernatural that was published after 10/31/17.
Book suggestions: too many to count, but I am personally looking forward to reading Tricks for Free by Seanan McGuire, which was released on 3/6/18!
Genre: Suspense: anything that fits into the suspense genre.
Book suggestions: again, this is a broad category - there are so many available books. I haven't settled on anything to fill this square. Our Suspense list is the cannibalized Romantic Suspense list, so if you have additions that are more generic, comment on the list, and MBD will add them when she has time!
