Just a head's up, I'm not putting spoilers on anything.
One statement; well actually two, that Harry makes that I found interesting was Harry's understanding or need to maintain a schedule to keep some kind of grip on himself. I think this can come from two sources. One was how Harry fell apart after Susan was infected by the Red Court. Harry was a complete mess at the beginning and through much of Summer Knight. He doesn't want to fall into that pattern again. The second source that drives Harry is he is a father and recognizes his responsibility to Maggie, but he has also taken on other responsibilities as a protector of people around him. Being the Wizard of Chicago, whatever that will come to mean. I know from my own experience that focusing on a job at hand, putting food on the table and carrying out other responsibilities; while it doesn't help you heal from a tragedy, it can help prevent you from sliding further into despair, at least to a degree.
The second statement was that Harry recognizes that he will heal because he has done so before. At the same time, even though Harry knows he will recover, it doesn't make what he is going through any easier. Grief, and beating yourself up, wondering about what you could have done differently, are an incredible bitch to get through, as many of you know. Harry doesn't wonder what he could have done differently in this chapter, but he always does that and there is no reason to think he won't do so again.
For those reasons I found this chapter to be spot on. About the alarm clock, there are multiple possible answers to that one. He bought a new one, someone else got Harry a new one, the old one had been down in the basement lab and without thinking Harry threw it in with his other stuff that he buried in Lea's garden, the when police and FBI invaded his place in Changes. In fact, Lea should have returned all of that other stuff to Harry by now. It's a very small issue, both literally and figurately, to concern me.
Side note: I have a feeling we may get another chapter or two pre-released before the book arrives. Jim is pretty good at writing set up chapters that won't spoil the rest of the book if you read them early. I won't be surprised if these preview chapters end just before Harry's first date with Lara. I remember that for Cold Days we received several early release chapters the ended just before Harry's birthday party started in Arctis Tor.
