Try Jodi Picoult! She wrote My Sisters Keeper, which was fantastic, and I don't even think that was her best one. Change of Heart, 19 Minutes and Handle with care are just a few of my favorites. But warning!: They will make you cry lol. A lot of the time they have to do with intense stuff like murder, rape, suicide, school shootings, disease, etc. and usually involve a court case. Definitely my favorite author. Plus she has a few lifetime movies which are always fun to watch after you've read the books!
