I listened on audio, I liked the audio! I felt like some of this was like Perks of Being A Wallflower and it's kind of a funny story. I wish there were more sci fi to it but I understand how it could be like a metaphor. The grief was strong. Charlie and Zoey grieve, Henry grieves as well as his mother over her mother who has dementia. I liked Henry and Diego's relationship, it was nice and I liked how Diego treated Henry opposed to Marcus....hated him.
