I recently watched the Netflix series Stranger Things. Beyond the sci-fi/fantasy aspects, one of the things I really liked about that series was that many of the main characters were these young adolescent boys who were geeks. The Impossible Fortress reminded me of that aspect of the show. Our narrator and main character, Billy Marvin, is a 14-year-old in 1987, the setting for the novel, and is a computer geek at a time when a home computer means a Commodore 64 and text-heavy video games. That may mean more to some readers than to me; I was 28 in 1987 and wasn't interested in computers or video games. However, Billy and his friends remind me of the character types were used to in films and stories celebrating the '80s. And I'm always a sucker for stories about teenage geeks (I've definitely been there). Billy and his friends hatch a plot to steal copies of Playboy (the one with naked pictures of Vanna White) from a local store and things go awry from there. This was a quick, easy read that was a lot of fun, even if the computer coding and video gaming were things I wasn't ever into. The setting wasn't always clear to me - a small town (?) in New Jersey, just five miles west of Staten Island. The downtown is a two-block stretch of mom-and-pop business, with a Chinese restaurant, a movie theater without enough letters on its marquee, and a typewriter repair/office supply store that play a major role in the plot. But at one point we're told that there's heavy traffic through the area, which didn't strike me as logical given the small town description; the local cop walks a regular beat downtown, for example. I'm sure that this exists in suburban Jersey, but as a Midwesterner, I just couldn't get a good sense of that. There were a couple of stand-out scenes for me, though. In one, Billy is being questioned by a couple of cops about the break-in, and he thinks they're on his side, being friendly, and if he just tells them the truth, everything will turn out all right. His naivety is striking. In another, Billy's at the movies with a girl and he reaches over to hold her hand. She accepts that, and he realizes that his arm is at a weird angle and very uncomfortable, but he doesn't dare move it because he's holding her hand. A great description. Overall, I'd rate this at 4 1/2 stars.
