this didn’t land with me as much as her other two books, (likely due to its aim towards a younger audience) but i enjoyed it just the same. i think taking a look at the table of contents (thank you for having one, my god) will be able to help you figure out if the book is for you. 

it features very graphic descriptions about death, corpses, and decomposition, but i figure you wouldn’t have picked this up for any other reason.
