Each season, find one author who’s born under the star sign you are currently in and read one of their books. IE, for Taurus (April 20th - May 20th), authors include: Charlotte Bronte, Vladimir Nabokov, Shakespeare (apparently???).  Pro-tip: if you feel stumped, you can tackle two challenges at once by going through your TBR and figuring out the birthdays of each of the authors on the list.
