I'm really torn over my rating for this. There were so many things I thought were really strong, yet some glaring things that ruined a full 5-star experience for me. 
 

My main issue is with the timeline at the beginning of the book. In May, the main character goes back to the hospital, and writes that it's 'been a year' and everything is 'crypt-like'. She only wrote about getting sick in Feb, how has it been a year?? If she meant 'it's been a year' in a saying way, like it's been a tough year, then why was the hospital crypt-like after only 2 months? There was also someone later in the book who in the first July had had one 7-month pregnancy and one undetermined length of pregnancy (both by captors, not in her ‘previous’ life). That means everything started happening waaay before Feb, at least in the November of the previous year, which I don’t believe fits with the mc’s storyline. Either this is a mistake, I've completely misunderstood something, or the timeline is just fucked. 
 
Also, I believe the surviving baby at the end of the book would have seemed much more powerful if we didn't already know that the human race was going to survive. I think it would have been better if the prologue with the scribes just didn't exist. It didn't add much to the book, and essentially ruined the ending for me, as the birth was the capitulation of everything, and we basically already knew the outcome. This also meant that the tension/suspense wasn't as high throughout the book, as we knew the human race was going to survive from the beginning, so it didn't feel as fatalistic as it could have done.

 

Also, the font chosen for the Kindle version was REALLY hard to read. I was having to expand the font size two or three points just to be able to barely read it, which I think stilted the reading experience.  
 
On the plus side, I really enjoyed the concept and how the book was written. I appreciated the nods to the LGBT community, especially to trans men, and it made me realise how often authors don't make reference to anything in the LGBT community, even in passing. (Though it was have been interesting to see the impact of the disease on trans people, I'm hoping to see this in the next book/s.) I liked how we were told the endings to side character's stories, it was a nice change from so many books where you never get answers. It was also scary (yet impressive) how many things the author got right about pandemics, and especially the modern reaction to them, all the way back in 2014.
