Apologies if this isn’t the place to ask, but when I was young I read a book with the above premise. I thought it was just called “Coaster” or “Coasters” but I can’t find it anywhere online. I know at one point they go to Kennywood in Pittsburgh and ride the Thunderbolt, but that’s just one of many, I think. Anyone familiar with a book like this? TIA
