I did enjoy this Medical Thriller/Post-Apocalyptic book. The 1st book the main character is Dr June Mannis is trying to save people as the CO-D4 virus spreads when she finds some Codies (zombies) are not violent instead rectifying them. In the 2nd book the main characters are Tom Leland and James Ung trying to follow Dr Mannis theory trying to save humanity. Recommend if you enjoy a different Post-Apocalyptic book. I was given this free review copy audiobook at my request and have voluntarily left this review. THANK YOU!
