These are all the series I am currently in the middle of that are all complete (meaning all the books in the series have been published). Most of these I have either only read the first book in the series or I just have to read the last book. Completing most of these series is kind of a goal of mine for 2021 as well so it will be nice to look back at the end of the year and see how I fare!
