Last year, I attempted
PopSugar's 2015 Reading Challenge (and they've
another one for this year). It had 52 books on it (including a trilogy), and although I read 73 books over the year, I was not able to check off 14 of the categories they listed.
I've decided that I don't really need help picking out books to read - I have
a ginormous to-read list - so I've chosen a smaller reading challenge for this year, from Modern Mrs Darcy, just "read 12 books in 12 different categories in 12 months."
