For a first novel, this is a complicated story to pull off, with many loose ends to tangle together.
Poor Kate can not catch a break. Her car is on its last legs, when she decides not to give in to her bosses demands she becomes unemployed, and while this gives her time to follow her dreams and rehab houses, it doesn't equate that she has the money to do it. She is very good at her work, but has to sell one house before buying the next, AND it would be nice to have income to cover the usual expenses of living day to day.
A complication arises on the very first page when a body is found in Kate's rehab house. Even worse, there seem to be ties back to her former employer. This helps the local sheriff move Kate to the top of his suspect list.
This has the qualities one looks for in a cozy mystery, characters with distinct personalities, a small town or close community, a best friend who has the protagonist's back no matter what, and some gentle romance or personal interest. I wasn't immediately drawn to Kate and her friends, but the more I read, the more I wanted to understand how all the different angles would come together. The ending is quite dramatic and fast paced. This mystery gets solved and loose ends tied, yet we know there will be more adventures for Kate to come.
