The "Twilight" saga may be ending this week with "Breaking Dawn -- Part 2" -- but there's already another epic love story on the way from the woman who created Bella and Edward.

This morning, the first official trailer for "The Host" -- based on Stephenie Meyer's book of the same name -- was released.

The flick, starring Saoirse Ronan and Max Irons, takes place in a future where parasitic aliens try to take over all the human bodies on Earth, a la "Invasion of the Body Snatchers."

Like the relationship between Bella and Edward, the central love story in this movie is also forbidden ... as one of the aliens falls for a human.

The sci-fi flick definitely looks like it packs a lot more action than the "Twilight" movies, with explosions and high speed chases.
