On the positive side, I've never hate read a book as fast as I got through this since Verity. 

The Twin is a YA mystery by Natasha Preston who is obviously way too old to be writing the genre with how out of touch it was. Think of Steve Buscemi with the skateboard pretending to be a teenager. The characters mock the MC for attending therapy after the death of her mother (literally nobody stigmatizes therapy but the elderly) and refered to the one character of color as having "African American" hair. Like girl please don't try and diversify your writing if you can't even do it right. Aside from being very clearly detached from actual contemporary teens (this was written in 2020 btw) the plot was embarrassingly predictable. Nothing was surprising. I read this just to be certain that it was as shallow and obvious as I suspected and alas! It was! Not a single character was written likeable or well. The overall message was not good and unrealistic. And the trope of evil twin is so overdone that you'd think that Preston would have had the sense to try and subvert that fact and maybe throw a real twist in here. Like honestly

I wouldn't have been surprised that maybe Ivy actually was the perpetrator all along and was just an unreliable narrator, but if that had been the twist, I'd respect this so much more than it actually just being Iris.
