Everything you need to understand or teach River Bodies by Karen Katchur.
In Karen Katchur's thriller novel River Bodies, a young woman named Becca witnesses a murder that is eerily similar to one that happened 20 years before in her hometown of Portland, Pennsylvania. Despite Detective Parker Reed's best efforts, the townspeople refuse to give up their long-kept secrets - secrets that would solve both murders. Giving up her secret means that Becca has to confront the past and the people she left behind in Portland. The first in the Northampton County Series, this book centers around the themes of rituals, coldness versus warmth, communication with nature, and relying on one's intuition.
