a new rule or one already in the mix so my mind tells me as i type - the middling 3-stars for books you know deserve better but in the moment leave you with a simple shoulder shrug; 3 stars for the academic books that warrant rereading in order to build ones knowledge in a dense area of interest (greek/roman mythos). 3 stars because i think i like it but i am very new to reading in verse and on balance inferno had holds more sway.
