Chapter and Hearse by Lorna Barrett

Tricia just can't stay out of trouble.  There is an explosion and someone dies, so it can't be an accident.  Her sister is on a book tour so Tricia is helping out with those shops.  All the characters lend something to the overall picture and Barrett does a great job with development and story line, so nothing goes to waste.  As you go through the series you get more from each character, but I don't think you would miss too much if you didn't read them in order.  Just a fun read, something comfortable to curl up with and get lost in for a while.
