The Lemonade War is indeed realistic fiction. It presents scenarios and conflicts that are plausible and could potentially happen in the real world, giving it that realistic touch.
It's hard to say for sure. If the lemonade is used to illustrate a moral or lesson in a fictional tale, it's fiction. But if it's discussed in a documentary or real-life account, then it's non-fiction.
I seriously doubt it's true. Stories like this often turn out to be rumors or urban myths. Without reliable sources or confirmations, it's best not to believe them blindly.
I'm not sure specifically as'make lemonade novel' isn't a widely known common term. It could potentially be about a story where characters make lemonade, perhaps in a metaphorical sense of making the best out of a sour situation, like the old saying 'when life gives you lemons, make lemonade'.
The story 'Lemonade War' focuses on a brother and sister rivalry in the lemonade business. It has elements of competition, family dynamics, and personal growth. The kids face various obstacles and learn important values along the way.
