Reread Grave Peril last night, and I have a potential query for placing it in October; Harry's last conversation with Susan takes place with her in a bikini outdoors getting some sun on one of the last warm days of the year - is this plausible for early October on the shores of Lake Michigan, and if not, would moving it back into late September make a big difference ?
Also, "Lydia", for whom I did not see a specific age but whom I was reading as around 19-22, remembers having had a prophetic dream of people trying to kill the President; her being old enough to have had that dream about the Hinckley assassination attempt on Reagan in 1981 also seems a bit of a stretch. [ Assuming she would have to be old enough to remember and make sense of it, and that that was not a dream she had when she was six months old or something. ]
Also also, is the last time Charity saw Harry, when Michael was wounded in some way, being five years before Grave Peril, worth including on the timeline ? The more I think about it the more I want to know what exactly happened then, and where Michael actually was during Storm Front and Fool Moon, it would be way out of character for him not to have helped in those situations if he had been around; if he wasn't living in Chicago then, what prompted him to move back, and where did Harry meet him in the first place ?
