My Query

Decided I might as well go for it and see what I can come up with. This is the summary part, and I'll have the personalized agent stuff and personal info and all that jazz too. So this is the query for my novel, The Keeper, and I could really use some feedback and critique. What do you think?
***George Shepherd is grizzly keeper at the local zoo, and,what's much more difficult, guardian of his sixteen year old niece. After sevenyears he believes he's finally balanced the muddy claws, menstrual cycles and apast mistake he doesn't ever expect to escape.
Then a little boy shows up with the news that on Cindy'sseventeenth birthday, she will be taken as a princess by the prince of anotherworld. This is easily dismissed. He pats the boy on the head and takes himhome, hoping Cindy didn't hear anything.
At worst a sick prank, he thinks. Until things start turningup that can only be construed as evidence: symbols, letters, dreams, animpossible painting. With the help of Cindy's former teacher, he knows he mustdo whatever it takes to make sure Cindy is not in danger, even when it meansdirectly confronting the past he's tried so hard to bury. All before the leastmomentous birthday he hopes Cindy will ever have.
Part mystery, part romance, with a dose of magical realismand mid-life crisis, the true heart of this story is the exploration of whatkeeps us going when we lose it all, and the fine line between holding on fordear life and just letting go.
