2) Mental illness representation. This is basically the same idea as the disability rep, but I'm pleased to say that there are more books on mental illness than there are on physical disability, at least. I especially go for books on OCD or bipolar disorder, because those are particularly important to me, and I'm least likely to go for one about an eating disorder, because there are quite a few of those.
4) Magical women. This is one of my most beloved tropes. If I read a book summary that seems to indicate a lot of female power in the way of magic, I want it. Witches, goddesses, chosen ones--if there's lady magic at the forefront of the story, if women get to channel the spiritual and ethereal, I am there.
5) Telepathy/empathic powers. My love for the magical women trope is extra doubly true if the magic in question relates to mind-reading type powers. I always go for books about women who can read minds/hearts.
6) Complex family dynamics. If a book summary indicates that the character deals with complex or difficult family situations, that's another aspect that will get me on board. Family is such an emotional and important topic, so I'm always pleased to see a focus on sibling or other familiar relations. Furthermore, the power of family life makes it all the more vital that we discuss the darker or harder aspects of it. Plus, this adds a strong psychological/social component, and I love analyzing humanness.
7) Domestic violence/abuse. In conjunction with the above, I have a particular interest in books examining domestic violence or abuse of all kinds, especially if the characters overcome that abuse in the end. This applies to romantic relationships as well as family dynamics, and my top priority is books that focus on emotional abuse, since that's a little known and oft-dismissed problem.
8) Psychological/sociological concepts. If the book description includes the word "psychological" or something similar, I'll probably pick it up. I really like psychology! Psychological horror, psychological thriller, a contemporary novel based off of a psychological experiment: yes, yes, and yes. Along with psychology, I have a vested interest in sociological topics, so if a book promises a good analysis of social issues, like racism or sexism, I'm likely to give it a read.
9) Fake or arranged relationship. This is a classic romance trope that I love, and I pick up these kinds of novels all the time. Drama! Sexiness! Fun times!
10) Girl games the system by dressing as a boy. I told you these were mostly from my "tropes" post. Give me a girl using some well-picked clothing and a lot of cleverness to overcome a system set against her, and I will be there.
