Kinder Wells has built the perfect life caring for four-legged guests at Pooch Cassidy's, her beloved boarding kennel in Ricochet, Utah. Named for the German word meaning "children," she's always been drawn to protecting those who can't protect themselves—a calling that kept her sane through a childhood marked by her father's drunken rages. But when her abusive ex-husband Jackson turns up dead in her kennel area, the sheriff's investigation points straight to Kinder. After all, who else would know that oleander could stop a man's heart? Who else had motive, means, and a storage shed full of homeopathic remedies made from the world's deadliest plants? As evidence mounts against her, Kinder realizes the real killer is counting on her homeopathic knowledge to be her downfall. Armed with her understanding of toxic remedies and their healing powers, she must uncover the truth before she loses everything she's worked to build. But in a small town where secrets run deep and everyone has something to hide, proving her innocence may require confronting the one thing she's spent years avoiding—the dark legacy of violence that shaped her past. With her loyal orange tabby, Sundance, and her beloved shepherd Cassidy as her only allies, Kinder races to find the real murderer before the law closes in. Because in this deadly game of homeopathic cat and mouse, one wrong move could be her last.
