House Sitter Mysteries Books in Order

House Sitter Mysteries trades witches-first chaos for a more modern amateur sleuth setup. Penelope Bridges has spent twenty years keeping a billionaire's life organized down to the last detail. When she finally does something for herself, she chooses a new career that sounds peaceful, house-sitting her way from one gorgeous property to the next.

Peace does not last. In A Case of Sour Grapes, Penny's first assignment takes her to a smart-home winery in Sonoma Valley, where a famously disliked winemaker ends up dead in the cellar during a storm. That setup tells you exactly what kind of sleuth Penny is. She is methodical, observant, organized, and almost impossible to rattle for long.

This series is less about discovering magic and more about putting a highly competent woman in polished new environments where everybody is lying. Each property can bring its own cast, secrets, and local tensions, which makes the travel angle part of the fun.

If you like cozies built around capable adults instead of accidental chaos, House Sitter is a nice change of pace. Penny is still warm and relatable, but she feels like someone who has spent years keeping other people's lives from collapsing, and that turns out to be excellent murder training.
