Seeking a little help on a query letter! #amwriting

I'm sitting here, watching my fish chase each other around the tank (while she was visiting my mother pointed out to me that one of my fish is a real B----...I'm afraid she was correct!), and trying to put together a blurb for my WIP. I recently managed to get through the first serious overhaul of it and it's usually my habit to take a breather and work on something else. But while the story's still fresh, taking a crack at the blurb portion of my query is often really helpful. Though, honestly, I suck at writing these things, so if you have any comments at all, I'm definitely soliciting some help :)

This is for an NA paranormal, currently titled Coincidences:

Some might call a coincidence a fluke, luck, or happenstance; Ami calls it her job.

There are some coincidences that are too important to be left to chance and Ami and her partner, Luke, make sure everything goes according to plan. Ami loves getting two strangers to meet out of the blue, ensuring something isn’t lost, or the hundreds of other little events they facilitate. So when they’re tasked to stop a massive bio-terrorist attack in San Francisco, Ami’s more than a little worried. Then there’s Luke, her best friend since forever who is unexpectedly dating Ami’s roommate and stirring up feelings Ami never knew she had—mostly jealousy. With the clock ticking down to the Fourth of July celebration and planned attack, Ami and Luke have to piece together how to stop the release of the pathogen, escape the unwanted attention of lurking FBI agents, and face their feelings for one another. With millions of lives hanging in the balance, they’re going to need more than a coincidence to pull it all off.
Ummm, yeah, not sure that's working at all. Thoughts? Why is it so dang hard to get 75k into a couple of paragraphs??
Okay, and just for fun, here's Watson the fish moving rocks! LOL! (She's not the B--- either, just to be clear :)
