So... I might be stuck with what to write for the Hidden Wishes series book 2. I mean, I know the start (written) and I know my end, I even know roughly the theme. Everything in the middle is a GIANT blank.

While I am a panster, this might be a bit too blank. The last time I wrote without even a vague direction, it was book 1 of this very series. And it has the lowest ratings of all my books...
