Twisted Prey

Twisted Prey, the twenty-eighth book in John Sandford's series of thrillers featuring Lucas Davenport, will be released on April 24, 2018 in the United States and Canada, with a tour starting at the same time.
The tours have been getting shorter in recent years, and this one follows that trend. The author is 73, and while he's in good health, the tours are brutal.
At this point I don't know where the signings will be taking place, or even what cities he'll be visiting. But there are a few assumptions I can make safely:
The tour will probably start at the Poisoned Pen Mystery Bookstore in Scottsdale, Arizona. That signing may actually take place one night before the official book release — don't worry; the publisher is okay with it — but then again it might not. I don't know yet.
There are also several signings in the Twin Cities, but I don't know where any will be specifically, except that at some point he'll have a signing at Once Upon a Crime in uptown Minneapolis. He's always had a signing there, for every book. This time will probably be no exception.

And now, a few pointers in case you're new to book signings:
First, keep in mind that not all bookstores follow the same format, and some may have restrictions on how many books you can bring for signing, or other rules specific to that store. Always check in advance.
Also, if you are getting a lot of books signed, it's customary to wait until the majority of the other attendees have gone through. This is basic decency.
Not every signing has an open Q&A — most do, but it's not guaranteed — but usually the author will have a moment for a question when he's actually signing the books. Don't take this opportunity to start an in-depth conversation. Be considerate of people around you. This is especially true for the lunchtime signings, which take place during the lunch rush; many of the customers are on a lunch break from work, and they're in a hurry, and they don't have time to wait in a huge line. Those events tend to be signings only. The author may linger after the events and be able to talk, but please be considerate of those people who can't.
