Check out the Drop the Needle critique session Authoress is hosting over the next few days (including a few lines from Bob--he's #11). These submissions are 250 words that represent danger in some way, and critiques should focus on the tension and pacing--and of course, whether (or not) you want to read more.
Definitely head over there and share a comment or two. Or ten or twenty. Every comment will be helpful; I know I'll be looking for all the feedback I can get. And if you're a regular reader of mine, don't feel like you have to sugar-coat anything you might say about Bob. He's pretty tough--and we both know that any criticism you have you only share out of love:)
