To clear something up, when I say "a heart that will soon cease to beat", I'm talking about how Edward is going to change her into a vampire, which goes along with the "sooner rather than later".
And the worrying is just normal stuff, if/how to change Bella, Edward trying not to kill her, fighting the scent of her blood kinda stuff.
And the first poem is what Edward is writing to Bella, the second is Bella writing to Edward.
Soo, hope you like it, review please!
