This is a story set in a future where antibiotics are no longer effective due to overuse. People over the age of seventy are refused healthcare and end up in hospitals called waiting rooms.
I found the description of the ageing effects on people approaching seventy went overboard, almost like the book was originally written about people in their nineties and got hastily edited.
A significant amount of the story takes place pre-crisis, with two characters discussing the unequal impact of TB across the world and working on a cure by researching plants. However, the actual research, and in fact most of the story, falls away as it turns into a love story about an affair. I found this a bit much, with the main character acting like a lovestruck teenager. I wouldn’t mind but I felt it really got in the way of the world-building and the story.
I found the second half of the book more engaging as the story threads started tying together. There was a particularly sweet scene between the main character and her daughter. However, the end itself got pretty silly with bunny-boiler style murderers and secret service agents turning up to funerals.
