I Thought It Was You, by Shiloh Walker, from Samhain Publishing, which probably means it's erotica of some sort. #2.5 in Grimm's Circle series.

UK) and also
Amazon (available to Canadians & in the
UK),
Kobo &
iTunes &

Product Description
The events of this free short story take place between the events of No Prince Charming and Ren's story, Crazed Hearts. It turns out both Ren and Elle had some loose ends they needed to tie up-and that's what this story is about. It's not Ren's happy ever after. That's in Crazed Hearts.
Warning: the following story contains some unfinished business, some unrequited love and a whole lot of action between 3 somewhat debauched guardian angels.
Another erotica novel previously offered elsewhere is also now free in the B&N store.
All in Time by Ciana Stone, from Ellora's Cave,

Interestingly enough, B&N seem to have switched back to sending PDB downloads to website users, at least for these two, which also happened to be DRM-free, at least for the files that I just downloaded.
