an oddly liminal book: somewhere in-between novel and graphic novel, somewhere in-between YA and middle grade, somewhere in-between me liking it and me being indifferent towards it. 
 as a designed physical object, itaEUR(tm)s impressive. itaEUR(tm)s solid and heavy and fits nicely in the hand, the cover is subtly embossed and the cover image is seductively spooky. all good things. itaEUR(tm)s also a breeze of a read, as half of the story is sequential art and the other half is diary entries. oddly enough, the portion without words takes longer to aEUR~read,aEUR(tm) because you wanna absorb the details and look for additional clues. but being pretty and fast isnaEUR(tm)t everything, as many high school girls learn soon enough, and this one doesn't have lasting appeal. also like high school girls, this is for a younger-than-me audience, so keep that in mind, but i had a few complaints. 
 i thought the artwork was iffy - sheaEUR(tm)s really good at landscapes and inanimate objects, 
 but her humans/former humans donaEUR(tm)t always pull their graphic weight. 
 which is frustrating and disappointing, because sometimes she does it really well 
 and sometimes itaEUR(tm)s all unformed and meh 
 that profile is bananas. 
 and as a general rule couched in a very specific example - if youaEUR(tm)re going to show a picture of a door that is meant to have a word scratched on it, even if that detail hasnaEUR(tm)t yet come up in the story, you have to either show the word or make different decisions about your composition, because its absence will be noted during a second-read. 
 as far as the story, i dunno. a lot of it is pretty standard slumber party stuff, but i appreciated how this one was more bittersweet than horror. itaEUR(tm)s a story of bullying and loneliness and grief and why parental supervision is a thing that matters. but thereaEUR(tm)s still some stuff thataEUR(tm)s unclear to me. 
 boring nitpicking begins: 
 because - back to that door-scratching - it seems like thereaEUR(tm)s some ambiguity around whether her little nemesis was the one doing it. from the beginning, i suspected it was someone/thing else, because it didnaEUR(tm)t seem to be in keeping with her usual MO, which had been more geared towards big demonstrative bullying with instant payoff rather than chinese water torture/psychological breakdown. i mean, who wants to stand outside someoneaEUR(tm)s door all night scratching like a tailypo when itaEUR(tm)s so much more fun to cover a girl with gravy in front of all her peers? so i assumed it was some kind of ghostie trying to make contact with mary that would then daisy-chain into the future with ella & etc, establishing some sort of lonely-kid ghostie club stretching back over the years. but, no.
