Many parts of New Orleans, where this book is set, are below sea level. That can cause problems, to put it mildly, especially during hurricane season. But this book will cause very few problems for readers. The dialogue is conversational, the plot is fast-paced, and the words and sentence structure are very easy to understand. Nick sometimes lapses into colloquial speech, and he sometimes uses double negatives, so don't look to him as a grammatical role model. But it's not like anything he says is hard to understand.
