Nina Soni, sister fixer

"A long rainy stretch during spring break has Nina restless and hungry for a new project and aggravated with little sister Kavita's embarrassing behavior. A fresh pile of dirt just delivered to the neighbor's house for a landscaping project ends up being too tempting to resist. Can Nina fix Kavita and create something amazing at the same time? With her sister's help, Nina launches a grand engineering project--with unexpected consequences."--Publisher's description.
