Art done similar to this (or like many books out there right now including 50 Shades, etc)
Image would be pen laying almost laterally, held delicately by a man's strong hand but gentle grip, NOT like he is using it as a stabbing instrument, but NOT like he is writing with it either.. almost half between that he could go either way in a split second.
The pen is dripping red ink that looks like blood but at first its coming out forming little hearts, but as it streams to the puddle/pool below, the hearts turn into daggers. The transition from hearts to daggers would have to be subtle... but noticeable.
The two things that should catch my eye (I would think) would be the silvery tip to the pen that would make it look sharp even tho its not, and the somewhat large pool of ink/blood on the bottom (I may want to use the bottom of the pool to frame a subtitle, my name as the author, etc.. )
On right side there are just enough jail cel bars to show an arm extending thru the bars holding out an engagement ring (like he is proposing thru the bars).
On the left side is me, either a photo or a character drawing of me similar to the one of me at http://www.teresastales.com where I am holding a torch.
However, in this drawing, I would look confident, yet skeptical, curious, yet hesitant... maybe with arms folded and foot out like I am saying "give me one reason why I should". yet I have that look like I already know I will, I am just playing hard to get.
In this image, it should basically BE the hook that draws the reader in to find out what he said/did to convince me to marry him.
