You know all those book series that you started, but never finished? Do you ever feel guilty when you start a new series even though you have all these unfinished ones? 
Now’s your chance to finish them!! Make it your New Year’s resolution!!
Add the last book of a series you haven’t finished onto each challenge!
Honestly even if you only finish one series or only read one more book in that series it’s still a success.

Please note this is only for series that you have started in 2023 or before, not for new series started in 2024.
