I love the idea of a story that deals with how a city hospital battens down the hatches to survive an apocalyptic event. There are definitely some good characters. My beef with the story is that I believe the characters, who are obviously smart, generally reacted unrealistically.or foolishly to their situations with unlikely outcomes to ther reactions. Also – the characters seemed generally uninteested in what caused the EMP. There is no explanation for why the plumbing still seemed to work, and the police never make an appearance. AND I have to wonder where the general popualation went — the only people mentioned had relevance to the plot. The author writes well – I would just recommend that she consider if somebody is pointing a gun at you and say they are going to kill you, maybe the more realistic (& smarter) action would be to kill the threat at your earliest opportunity instead f disarming the threat and shooing them away.
