It's the Rounders' last season together, and they want to go out with a bang. Especially Slingshot Slocum, the team's star pitcher. So why has he just walked three batters in a row? Slingshot's obsessed with mastering the forkball - a dangerous split-finger curveball that everyone knows should never be attempted by anyone under the age of seventeen. It could wreck his arm forever! And he's not making it over the plate. Just like the torrential weather, Slingshot is all wet! The rain won't stop pouring down, and the Rounders' season is starting to feel like an airport during the nothing but delays and cancellations. At least they have their team rafting trip to look forward to. Until a flash flood sends them careening straight into the middle of a real-life ghost tale. Can the Rounders pull themselves out of peril - and their pitcher out of his funk - before their final showdown with archrivals the Haymakers? And will the weird weather let up or rain on their parade? Looking for hilarity, high stakes, high jinks, extreme weather, and some spooky spelunking? Catch this action-packed baseball adventure!
