I'm looking at two different reading challenges for 2019: The BookCrossing Decade Challenge and the PopSugar Challenges. (In the PopSugar Challenges, you can use a single book to satisfy multiple prompts, so if your South American author writes a book with a two-word title, you've filled two prompts.) I may not complete either challenge; I hate it when needing to read a challenge book interferes with wanting to read something else. I also have a bunch of unread targets from the Great American Read I hope to work into these challenges.
