Vivian Van Tassel is an angry young teen. Part of this is justified: her mom recently died and she blames herself. But as we quickly learn, Vivian has had a temper for a while (and as a parent, I’m genuinely concerned that she’s never been in therapy for this, either before or after what happened to her mom.)
Anyway, it doesn’t help her any when her journalist father decides they ought to leave their Chicago home and move back to her mom’s hometown of Midnight Lake, Wisconsin. Her mom’s ancestral home is falling down and her hapless father has little clue how to fix anything, and has taken a significant pay cut to come work at the local paper besides. Starting at the middle school is awkward enough even without the popular Amber Grausman deciding she hates Vivian. The school is a converted sanatorium, and the teachers almost uniformly mean. The few bright sparks are an understanding history teacher named Miss Greenleaf and a group of welcoming nerds who play the role-playing game Beasts & Battlements (B&B for short) that was actually written and designed in Midnight Lake decades ago by the late Garrison Arnold.
When Miss Greenleaf assigns the kids to research various local institutions to drive home the impact of history on the living, Vivian begins to learn a lot more about the curious past of Midnight Lake. Worryingly, she begins to see parallels between historical incidents and the goings-on in the B&B game she’s been reluctantly observing. As people start to go missing and dead creatures begin to mysteriously appear, Vivian will find herself plunged deeper into the secrets of her new home, even as her own bad temper continues to get in her way.
