Dead Before Dinner - A Maddie Swallows Mystery, #1

Green chile has never been more dangerous. Psychologist Maddie Swallows has done something she swore she'd never do. Return to her New Mexican hometown. It seemed like a good idea at the time, considering the divorce and her two teenagers she dragged along for the ride. But that was before the New Year's Eve party she was guilt-tripped into attending. Before a member of the town council wound up dead and everyone at the party became a suspect.
And before she was forced to unravel the secrets of her former home in order to clear her name. Of course, with the help of two precocious teenagers and one meddling mother, the real murderer doesn't stand a chance.
