I love epistolary novels and the premise of getting all the clues to solve the mystery, so had high hopes - but this was just okay. It started off interesting enough, but I kept waiting for it to get going and that never really happened. This was just intriguing enough to keep going, but man, it dragged on! Even near the end. I went back and forth between finding every single character annoying, and appreciating how real the characters were - especially with how clueless and unhinged Issy was, and how hilariously rude Sarah Jane was. (I mean, Sarah Jane was usually right, but her attitude was so off-putting). In the end, it wasn’t really worth it to wide through.
I also saw the “twist” about Poppy never being sick and the munchausen by proxy plot. Tish just seemed so sus so early on. Helen too. I also think adding in some last minute evidence was pretty cheap.
