Next?

I’m thinking of starting a new novel soon. As soon as On The Sly is out to the beta readers. The rough draft will take about 40 to 50 days.
.
The question is, which one?
.
Wasteland has been at the top of my list for a long time now. It’s all thought out and ready to go.
.
But Sylvia, the mc in On The Sly, has really captured my heart. A second book is calling to me. Really hard. I have a rough idea of where I’d like to take it.
.
I’ll have to decide soon. I’ve finished my read through of OtS and I’m very happy with it. Just a few pacing issues to clear up.
