Just read one of the greats? Something that was maybe a little hard to get through with because of the themes, the writing style or the general length? I highly recommend a literary palate cleanser before you pick up your next tough read. Something easy that you'll breeze through - a book that can be read in a couple of sittings. Something you don't have to show off on socials or read in public but with rinse your brain clean of the previous read for the next one. I just read "Boyfriend Material" by Alexis Hall in a day as a car wash for my mind and it was perfect. Anything romance-y or soapy or aimed at young adults is perfect for this.
