I love the story, too, or else I wouldn't comment!
However, since editing is my life, I'd like to give you some constructive (read: encouraging!) criticism.
One thing people keep mentioning are the cliffhangers; they actually have me a bit perturbed. Honestly, everything I've read so far could have been part of one chapter. It's jarring to read it this way, all disjointed... When you're reading a good story, you don't want to be interrupted. I wouldn't actually call the method you're employing "cliffhangers" so much as "speed bumps." Personally, I'm getting tired of being jostled around! My point is, once you've got us in the action, keep us there. There's no reason to chop your story up this much. I would create some transitions between these chapters and join them together.
Other than that, this is awesome writing. It's rare to find a fan fic with good, solid writing that makes you want to keep going. Most action stories seem to get so bogged down in details, but you've got just the right amount of detail and suspense. I'm hooked!
