Once in a while I recommend something that's really only useful to local-ish folks and today is one of those days, so you're welcome or I'm sorry, depending on where you live!
We don't have a ton of independent bookstores in my part of the world (though where does, really?), so I'm delighted have discovered The Silver Unicorn Bookstore in Acton. It's been there for about six months, and it's got a nice selection of books for all ages plus the kind of cool gifty items you'd expect from an indie. And even better, they're doing lots of events - I've gone to one middle grade and one young adult event so far. The owner and all the staff I've encountered have been great, and they have a membership program I'm probably going to end up joining. Go check it out, and keep an eye on their calendar!
