The book opens with a famous actor, Arthur Leander, having a heart attack on stage while playing King Lear. Jeevan Chaudhary, a budding EMT and member of the play's audience, leaps on stage to do what he can to help. Caught up in this small but important drama to them, little do they know that a deadly flu is taking over the city of Toronto. Soon, one person's medical crisis becomes irrelevant when faced with a medical crisis for the entire world.
The book leaps backwards and forwards in time, so the reader slowly learns the reasons and backstory of what led the characters to the opening scene. The transitions are smooth instead of jarring, and the beauty of the tale is woven out of these time shifts into a bittersweet story that gives the reader pause, without becoming maudlin or pandering.
I won't reveal more for fear of spoilers, but this book was very hard to put down at all. I would definitely recommend it.
