"Genrify is a useful blog that celebrates great literary mash-ups that may have tricky genre labels, and helps readers and librarians find more of the same. [...] one of the best things about this blog is a tool called "The Blender." Their website explains: "The Blender is a tool meant to help readers find books that include more than one genre. [...] simply pick two or three genres you are interested in and click the "BLEND" button. Your results will include any title from the database that has the genres you selected.
