The silver moon of summer

"This summer, the town of Pruet is turning 300, and a huge celebration is planned. On their first night back east, the girls make a promise not to fight with each other, ensuring that this will be the best summer yet... With the divide between the girls growing deeper, Marigold, Zinnie, and Lily worry it's impossible for them to go a summer without a big fight. The same silver moon may hang in the night sky each year, but the sisters below it are changing in ways they have yet to understand. If they grow apart, more than a promise could be at risk. But if they grow together-the sky's the limit."--Publisher.
