Did you plan to write "Rachel's Peril" series when you wrote "A Song for Julia"? Or when did you decide to write the spin-off series? I'm just curious.
Hmm... no. I started thinking about the spinoff a while after I finished The Last Hour, so all three full length novels in the Thompson Sisters were finished when I started on the trilogy.
I started with Book 2 (Just Remember to Breathe) not even realizing I had a series on my hands. But it developed from there because I loved the characters.
