Well the actual storyline of this was fine, if very predictable. Apart from that, I don’t really have anything good to say. 

I found it weird that Jenkins Reid chose to name two characters Carrie in her ‘universe’, both with main plotlines of affairs. 

I thought it was extremely unrealistic for the letters to include the amount of detail they did, especially when it was a character describing in detail an event the recipient was also present for (e.g. the first time both of them met). 

Also, at one point Carrie cays she’s the only person who takes in the mail at her house, and we’re told she’s in the house most of the time. So HOW has she never noticed any of the other woman’s letters being delivered?? 

And David sending a POSTCARD to Carrie? As in a postcard that doesn’t have any level of privacy, so anyone could see what was written on it before it got into her hands??? Wild.
 
 And what the fuck is 'the twist' that so many of these reviews are on about?? Is the twist the two people who were very obviously having a sexual affair having a sexual affair? Or that, shock horror, it was Ken with the fertility issues, and not Carrie? Wtf. 

On a format note, italics being used for some lines in a handwritten letter?? As if. 

And the different font sizes used in my Kindle edition for the different letters was ridiculous. To not have to change the font size every other page I had to have the normal writing MASSIVE and all the other fonts still pretty tiny. The ebook formatter dropped a massive fucking ball there. 
 
So a mildly enjoyable read, with massive believability issues. Not what I expected from an author I usually enjoy reading from.
