I've loved John Green since reading Paper Towns in 2008. I was thrilled when The Fault In Our Stars received its deserved accolades (and a great movie adaptation to boot). So it's no surprise that I'm squarely in his corner on Turtles All the Way Down. While this book doesn't have the emotional punch of TFIOS, it's similar to Paper Towns (or Finding Alaska) in that it uses a mystery (in this case, the disappearance of a billionaire) as its backdrop. Where it DOES remind me of TFIOS is in Green's handling of a serious illness - in this case mental illness (anxiety and OCD). He does a great job letting readers crawl around in Aza's mind so we can see how debilitating true anxiety and OCD can be. He wrote about it so convincingly that I googled and discovered that he has firsthand experience with anxiety and OCD - and speaks openly about the challenges they have posed. In addition to respecting his work and being a fangirl of the 99th degree, I also appreciate his willingness to help destigmatize mental illness.
