For every project I've ever written, I've had a playlist.
When I wrote movies back in the day and was working on a spy thriller, my writing playlist, which is not the same as my regular playlist, was jammed packed with every Bond soundtrack I could think of to get me into the right mind space. When I was working on a kids movie, I listened to songs from my childhood to get me to remember what it was like to be ten. And, when I was working on Sapphire #3, I listened to Glenn Miller and Hozier (I think a Glenn Miller song might actually be mentioned in the book) to get into Sapphire's father's two personalities--the social one, and the dark one.
As for Sacrificing Sapphire, the latest book in the Sapphire Dubois series, and soon-ish to be released (nope, sorry, don't have a date yet) I made this playlist.
