The dare is to jump from the garage roof into the above-ground pool, which is twelve feet away and four feet deep and has a crack in it that Denny's dad has been meaning to patch since June.
Trace does it first because Trace always does it first. He lands wrong and comes up holding his wrist and says it's fine before anyone asks.
Denny goes second. He lands in the center, clean, and when he surfaces he pushes his hair back and looks at Trace with an expression that is not quite a smile.
"Grandma would've loved that," Denny says.
Trace gets out of the pool. He walks to the garage. He climbs the ladder again.
"What are you doing," Denny says.
Trace jumps from the peak this time. He misses the pool entirely and lands on the lawn, which is dry and hard because it's August and Denny's dad hasn't watered it either. He lies there for a moment. A dog barks somewhere on the street.
"Good?" Denny says.
"Good," Trace says.
His wrist is definitely broken.
