Dalton's Last Stand (The Kingsley Twins Book 1)

Braggart Ralph Henry Dalton irritates even the new substitute teacher of Jeoffrey and Jerrianna’s fifth grade class. He’s a Class A Annoyance that everybody would love to blast into a black hole in the remotest part of the galaxy!
When an abandoned, but uniquely talented cat enters their lives, Jerri, the creative optimist, dreams up her “perfect” solution. Hold an air hockey tournament, Saturday, and set Ralph Henry up for the ultimate humiliation! Defeat at the paws of their seven-toed wonder, Snowshoe Mal.
Malley, however, doesn’t seem to like boys, and plays only if and when she feels like it. Pessimistic Jeoffrey only sees disaster in his sister’s plan.
There’s no way to skip by Saturday, so, Jeoffrey plots the next best thing—Malley’s disappearance.
With her gone, their mom, Northfield’s local champion, would have to agree to take the dumb cat’s place as Mystery Guest Player! Heh! No one’s ever beaten the great Kai Cei Jayne Kingsley!
Couple of things the twins didn’t anticipate:
1) that Ralph Henry actually IS deadly at the game
2) that, as children, the adults chaperoning this momentous event used to be friends and/or rivals themselves
. . . and it’s all coming back to them as the twins and their classmates battle on air cushoined ice leading up to the decisive match that may or may not put Ralph Henry in his place.
Could be it’s not just Ralph Henry who needs an attitude adjustment!
Yeaht . . . doesn’t it figure . . . Malley’s disappeared without Jeoffrey’s help.
