Shot Through the Hearth by Kate Carlisle

Shannon has been remodeling homes and building new ones since she was a small child working with her dad.  He's retired now and she's taken over the business.  She's on the biggest job she's ever handled and money is no object, so the situation is ideal for her.  Except when the big conference in the new facility is going, someone begins killing people...

Berkley and Net Galley let me read this book for review (thank you).  It will be published October 29th.

She hates that it happened at a site she works at.  The cops already consider her a body magnet and here's another one...

Then someone shoots at the group barbecuing outside in the evening.  They figure out where the shooter was standing but they aren't real sure who he was shooting at.

It gets worse.  They find a man strangled with a plant.  The man with her is crying for his plant but she had just been speaking to the victim earlier in the day.  Who would want to kill a nobody?

It seems that someone at the conference is a psycho.  Will they be able to identify him before more people die?
