Yeah, that's tag lines, not "tan lines". 
What I'm looking for is some feedback from other authors or editors on what works and what doesn't for your own tag lines. Let me preface this by saying I absolutely despise the tag lines I've come up with my first two chapters, and don't feel like my third is all that hot either - I feel like I'm being vague to the point of obtuseness in an attempt to avoid spoiling the chapter of the story.
Any tips for generating quality tag lines, finding the balance between not throwing spoilers out but not being too vague while doing it?
