I didn't care for how Blake found the pranks fun even though she says she didn't like them. I've never had any patience for pranks that involve physically messing with someone; most of these involved liquid, paint, or slime dropping on someone, which is just mean. If tweens want to read about this, that's fine; I just hope they don't attempt any of them.
This is somewhat similar to Kinard's 2012 The Boy Project with shades of Haddix's 2012 Game Changers and is a great addition to the WISH novels, which are super, super popular with my readers. I never understood the need to be popular, but it is apparently more of a concern than I thought, according to a random selection of 6th graders I polled.
Great examples of the self-improvement genre range from Wilson's 1957 Always Anne to Cabot's 2006 How to Be Popular to Moskovitz-Palmer's 2020 summer camp themed Camp Clique. This is being issued in paperback, so is a great choice as a gift for an avid reader who is starting middle school.
