This was a tired formulaic story that exemplified everything that's bad about series. I listened to the Ava and Pip original audiobook by this same author recently, and liked it, but this one, also an audiobook, was too much of a 'more of the same' story, which really had no story, and it was pretty much a cookie-cutter clone of the first volume in the series (this is volume 3 which I read out of order, but the order doesn't really matter). The reading by Kae Marie Denino was fine, but the story really wasn't.
In the first volume we had Ava making endless palindromes which was frankly a bit tedious because there were so many of them, but it wasn't awfully bad. There's more of that here, and it's really too much more in a second volume, and it becomes wearing rather than entertaining. Was there not another aspect of the English language the author could have explored here? Additionally, we have Ava once again doing something thoughtless, getting chewed out by other people, fixing it, and then becoming friends with the people who were extremely hostile to her just a short time before. This is exactly what happened in the first story. So what it transmits here is that Ava can't learn and is stupid, which is never a good thing to do to your main character, and it says, I'm making you, the reader/listener, pay a second time for what's essentially the same story with a few details changed, which suggests that the author thinks you're also stupid to fall for the same trick twice.
On top of that, there's the 'hey, I didn't know I loved my best friend' trope, which is tediously common in YA novels, and here it reared its ugly head in a middle-grade book. Again it says the main character is stupid to have failed to realize she has a special bond with her best friend. Even an eleven year old can tell that. It also says her friend Chuck is stupid for failing to realize this in return, and also that he's an insensitive jerk to hang around with Kelli, who is a jerk herself. When he quits seeing her (after too long) the book also says it's fine to lie to people since he doesn't tell her he's done hanging with her because she's a jerk, but because his mom said she didn't want him hanging with people in that way at his age. In short, he outright lied.
The text for the day here is also the same as the first volume, in that it relates to considering others' feelings, but the story actually undermines its own morality tale because, after having had people chew out Ava about her total cluelessness regarding body positivity, it still has her go ahead and put out a poster essentially saying, 'hey fatty, here's how to shed a few'. It's not that bad, obviously, but it might as well be.
So for me this book was a fail because it sent all the wrong messages and often contradictory ones at that. Ava's mother at times seems cruel and cold as well, which is frankly disturbing. Now I have the second book to get through, and I'm thinking it's probably also going to be a redux of volume one. We'll see. At least these books have the advantage of being short!
