Does it even matter what I say about this? You're either going to read it already, or you aren't; my opinion isn't going to make a lick of difference. 
 I went into this with mixed feelings and came out the same way. Have I outgrown John Green? If I go back and reread Paper Towns, will I be disappointed? It took me a long time to get into this one; I was only hearing Green's voice as his MC detailed her struggles with obsessive thoughts, and some of his politics through the character of the mom. (Green is male but the MC is female; does that make this a Mary Lou?) 
 There is the obsessive thought spirals, the hint of romance, the mystery of where the billionaire father disappeared to. It's a good book. But if not for Green's name on the cover, IDK that I would have picked this up at all, or stuck with it. (yes, I would have stuck with it, because I am super-lazy and didn't have another book within reach.) It's good enough but didn't really shake my worldview. It didn't thaw my icy heart. I'll be buying it for my 8th graders because of course they'll read it and love it, but for me? Eh. I'm glad it was a library copy, and I'll pass it along to the next person in line tomorrow.
