Brother and sister, Evan and Jessie
became a same class because
Jessie skipped a grade. And, they two
started to fight who is better at each other
by LEMONADE WAR.
But, in my case, I think book is
having a pattern. It's because
if Evan is winning the war,
Jessie tries to ruin, and Evan make a REVENGE.
In other hand, I liked describing
Evan and Jessie fighting by
the LEMONADE WAR.
