Hi Denise,
I'd planned on writing a short review on Face Up, but upon reading your first version of chapter 7 I did a raincheck and decided against. I didn't want to come over as trashing what you write, but I have this thing with truthfulness and I couldn't have given that ending good marks.
So, now you have made it easier for me, by rewriting the end, which is now much more plausible!
Soooo....
I like your protagonist, especially whenever she's interacting with someone else but Straker. Then Cait has pluck, mettle and is actually funny and gritty. Quite some potential there and I think it might be interesting to see more of her in future stories. That scene with Jackson was real fun to read, especially as Jackson also comes over as way more human than usually.
I'd love to see Cait less of a puddle at Strakers feet in the scenes with Straker though
I like some of the rather visual and tactile ideas in the story, like the treasures, the sort of items both of them gather as keepsakes, Jackson's spoon, Shannon's T-shirt for Straker.
I have my biggest problems with Straker himself, especially in the first version of the ending. He's quite simply too perfect, too sweet, that's better now insofar that he suggests she can go, if she wants that, almost again making a complete disaster out of his private life (as he did repeatedly in the series itself).
That discussion in the revised version works better. I probably would have preferred it drawn out into 2 or 3 chapters, possibly with Cait actually leaving him standing to reason it out with herself on her own. But any which way - this new ending is miles better than the first one now!
Lastly, I see lots of potential for further stories, especially with Shannon and of course with Cait's abilities (which I think are a nice turn of plot, given that she is from Scotland).
All in all, I'd say not your strongest writing regarding plot and plausability, but firmly in the upper third.
