When the world starts igniting and burning, Nurse Harper Grayson, tries to remain calm, helpful, and cheery, embodying her heroine Mary Poppins but as the virus that causes people to spontaneously combust gets closer she finds herself on a quest to find safety, a possible cure, the fantastical truth about the bacteria and a new family. A bit long but highly readable and although not as tense or gruesome as expected it was still enjoyable.
