This is a good piece of work or record, so I hold it to a higher standard than the usual stories here.

You're doing a good job here, but there were two parts of this story where I felt the narrative jumped ahead too quickly, like the DVD has suddenly gone to fast forward.

    Later that night, after Lara got home and went to sleep, she had a dream.  This glowing being who looked a lot like her - blonde, with the same pale blue eyes, only much older - appeared.  This being, who said her name was Shema, told Lara that she was about to reach her destiny.

    She opened her eyes, and Shema was still there, in her bedroom, only glowing much less. 

This is the first appearance of a MAJOR character and it's covered only in reported speech as a single context paragraph for the semi-waking scene that follows. If was was editor of this work I'd call on you to unpack that to be a scene in its own right, focussing on seeing Sheme for the first time from Lara's perspective and on Lara's emotional and intellectual responses. This is a key moment, and it sets up the punch of the semi-waking scene that follows when Lara's powers get unlocked.

Then we have another key meeting to set up:

    There was a recording.  It said to go to a specific address.  This was all very mysterious so far.

    Feeling adventurous, or at least like she’d gotten deep into this enough to see it through, she wrote the address on the back of the business card, and called a taxi from her home.

Minor point here, but it felt like pacing-wise it might have been good to hear the message and get a show-not-tell of Lara feeling adventurous. You do a good job of covering her other emotional progress in this scene, but it felt like this early minor beat was missing.

Now the actual meeting is the other major plot development and this scene was good, but it felt like there were bits that you wanted to get to so you skipped over some stuff so you could get the things burning in your imagination down in words. That leads to a few quick jumps, such as:

    The tall man held his hand over the glass, and it immediately filled with water cold enough to frost the outside surface.  “Would you like a drink of water?”

    Lara took a couple of steps closer, hypnotized by the filled glass.  She realized then what he was.  “You’re an elemental.  A water elemental.”

    Ã¢â‚¬Å“I feel like you’re one too,”  he said.  “What’s your element?”

In three paragraphs you hit the reader with three massive slams of plot-forwarding with no time to disgest each. Your story wants us to note three things:

1. Hey, this guy can make water appear in glasses! He's got powers too!

2. Lara somehow knows what this makes the guy, even though we've not really heard much about elementals yet.

3. The guy proclaims Lara is an elemental too! And it seems he's familiar enough with elementals to ask her about her element in much the same way as someone else might ask her birth-sign.

I'd recommend some reaction moments to each. The water-filling deserves a paragraph of its own, then a Lara reaction shot, then the guy's question about "Want water?"

Then we need some internal thought process for Lara as things click into place for her elemental revelations - perhaps a link back to the Shema meeting from the last scene?

Then we need the guy appraising her to offer his responses.

In other words, this important scene could be made more important yet in the readers minds with just a slightly more decompressed pacing.

The other thing that struck me as odd was that Lara had plenty of questions for this chap but never "What's your name." And after she discovers he's an elemental it goes right on to "Join our nameless team," She doesn't ask "Who else is on it? What do they do? Why do you need a team? Where do elementals come from? How many are there of us? How did you discover you could make water?" and a whole bunch of other queries from a girl who's depicted as whip-smart with an enquiring mind.

Even if the answer is "Tell you later when we trust you more" or something, it's reflect well on Lara to be depicted showing her smarts.

Now note I'm not slamming the story. I'm taking it seriously, because this could be your next novel. If and when you repackage it the things I've mentioned here are things you need to address in a beta-edit.
