JMB - thank you, an interesting point. To clarify, it isn't old for an elf at all, as they live to be a couple of thousand years old - but point definitely taken.
Here's another revision and pleased to say that it clocks in at 271 words with all my contact info, shortest one yet!

Dear Ms./Mr. Agent,
Overhearing she has an abducted twin sister Amanda is inconsolable. She is dumbfounded when her parents confess she’s an elf possessing immense magical powers. Yet taking on an uncharacteristic recklessness, fueled by the need to rescue her sister, Amanda kicks the intensity-meter up several notches. Making an already dangerous development of powers more life threatening than she realizes.
Prior to reality shifting dreams and a necessary relocation to the Elven village, Amanda’s heart was devoted to a human boy. But her rediscovered identity brings to life the intense and arrogant elven boy from her dreams. Amanda grits her teeth every time he swoops in to rescue her from her own recklessness. Yet it doesn’t stop her insides from taking roller-coaster dives when his smoldering eyes penetrate hers. Which causes an immediate reaction of guilt as Amanda begins to question her love for the human boy.
She’s quick to realize her destiny’s at odds with the desires of her heart. While her divided focus puts everything at risk: her life, her sister’s life and both the human and Elven worlds by placing them in a path of inescapable tyranny at the hands of her sister’s abductors.

Thank you for your time and consideration.
Sincerely,
