Paranormal Romance & Urban Fantasy discussion

I don't know if it is the right place to post this.

I need help with a blurb. I believe my original one is kind of bland and doesn't tell much about the story. I tried to re-write it to the norms of Smashwords which is below 70 words. (Short description) That doesn't leave much room.

I am seeking opinions as to know if the new one sounds better or if I should stick with the original one. Thank you for any input. (I'll need to work on the extended description too)

This is my old blurb:
When an untimely accident brings Alex back to Earth, he discovers a different kind of being he never knew existed. Widely similar to his own species, they have one thing that sets them apart—they feed on human blood. During his quest to repair his ship and return to his own world, he will come to realize that his unfortunate fate might not be a coincidence after all.

And this would be my new one:
When an untimely accident brings Alex back to Earth, a planet he visited in the past, he discovers a different kind of being. Widely similar to his species, one thing sets them apart—they feed on human blood. After a betrayal lands him in the hands of the humans, he escapes with a group of vampires. Soon, they realize only they stand against aliens set on Earth's annihilation.

Needs something more. You want to intrigue your readers not bore them.

Just my opinion

ok, I understand. How's this one?

When an untimely accident brings Alex back to Earth, the last thing he expected was to fall in love. The survival rules are strict; do not fraternize with the natives. After a betrayal lands him in the hands of the military, he escapes and frees the vampires held captive with him. Now, can they put aside their grudge against humankind to save the planet from annihilation?
