This is your third book in a series and you've signed to write two more books. What's your advice on keeping a series fresh and entertaining?

I prefer reading series to reading stand-alone books, and I think the reason for that is the same as for most of the other people who feel the way I do: we like hanging out with characters who have essentially become like old friends. It's human nature, once we care about them, to want to know more, to want to see what happens next. The trick is to keep the characters growing and developing, not getting stale, but at the same time keeping them true to themselves, to what readers love about them.

Basically, Avery and Derek's relationship is the backbone of the series. There are also a few secondary relationships that are developing over time. The mysteries are superimposed over the relationships, and they change in every book. In chapter 1 of each book, Derek and Avery take on a new project, the renovation of another house. Because the job is different in each book, and because the setting is different, each house is in a different spot surrounded by different neighbors, it isn't hard to keep things interesting. I always have an influx of new characters I can use, while at the same time I get to add in whoever I need from the secondary characters already established in the previous books. The houses are always different, and I try to vary the plots as much as I can from book to book, while staying true to the characters and basic premise established in the first and second books.

How long did it take you to write Plaster and Poison?

Publishing a book is a long process, and writing the book is only a small part of it. I'm on a six-month contract. It takes me roughly three months to write a first draft of the book. After that, I spend a couple of weeks going over it before sending it to my agent. Then I wait a few weeks to a month until she's had a chance to read it, and then I work in her suggestions. After that it goes to my editor, who has suggestions for rewrites, as well. After I do those, there are copy edits and line edits to get through. While all this is going on, the designers and marketing department at the publishing house work on the cover, the layout, and the promo. The whole process usually takes close to a year and a half, from the time I write the first words to when I have a book in my hand.

Can you talk about the renovation tips included in the back of the book?

Each book has a set of renovation tips in the back, for how to do some of the crafts and projects that Avery tackles in the course of the story. In Fatal Fixer-Upper, it was kitchen projects and in Spackled and Spooked, bathroom. In this third book, the main focus is on the bedroom that B&B owner Kate McGillicutty and police chief Wayne Rasmussen will move into once they're married and Derek and Avery have finished renovating the carriage house on Kate's property and have turned it into a romantic retreat for two. Avery is turning the bedroom--the whole house, really--into a pseudo-Parisian apartment, with a padded and upholstered wall behind the bed, skylights that look like balcony doors in the ceiling upstairs, and dripping chandeliers everywhere. The tips include upholstering a wall, turning a basic Shaker-style headboard into a romantic Gustavian-inspired bed, and how to make Avery's paper-flowers, pictured on the cover of the book.
