Ooh, and if you're in Portland and if you want to catch a glimpse of a Bart in the wild, I'm at Powell's Books on Hawthorne a couple of days a week. Good luck, but be warned: I'm easily spooked.
The good people at Powell's Books have posted their best kids' and young adult books of 2018 . . . and The Pocket Guide to Spy Stuff is on the list! (A big thank you to this mysterious "Gigi L.")
