From the book by Sadie Hartmann, which I recommend reading alongside this challenge. The basic structure is a 90 book challenge + 11 books by the featured authors (Adam Nevill, Alma Katsu, Ania Ahlborn, Christopher Beuhlman, Grady Hendrix, Josh Malerman, Paul Tremblay, Stephen Graham Jones, Tananarive Due, & V Castro). I have also added their top 3 recommendations as further bonus books.
