The author of the query featured just below this posting would like feedback on the following version:
Dear Agent,
Twelve-year-old Declan isn’t expecting any thrills on this field trip. A national forest with lots of boring moose hardly screams “awesome.” His dreary day gets a jolt when he glimpses a monstrous figure stalking through the wilderness. Seven-feet-tall and falcon-headed, the creature slips away before anybody else spots it. [I need to clean my glasses, I first thought that said "monstrous figure skater."] [Now that I think about it, would you consider changing your book so it is a monstrous figure skater? It's sure to be better than a seven-foot-tall guy with a bird head.]
Declan: Look, at 7-foot-tall monster with a falcon head!!!!
Teachers & the other 25 kids on the field trip with him: Where? Where?
Declan: Too late, it slipped away. But I saw it, I tell you.
Teachers: You know the rule, Dec. If you bring LSD, bring enough to share.]
With his two best friends, Declan follows the clues [feathers, talon prints, and massive bird droppings.] and finds the ruins of a long-dead civilization beneath the forest. They learn this advanced race once created human-animal hybrids. Led by the falcon-headed Ra, the rebellious hybrids seized control of ancient Egypt, claiming to be gods. After their creators banished them to the distant forest, the hybrids faced imprisonment in cold storage. Finally freed by a malfunction, Ra intends to salvage the technology and produce countless hybrid warriors, enough to enslave humanity. [I know you say "countless," but realistically, how many human-animal hybrids do they think it will take to enslave humanity? Humans with falcon heads aren't that scary. Falcons with human heads, on the other hand, can at least fly, so they might be able to enslave a few easily impressed humans. I'm not even sure human/lion hybrids or human/bear hybrids could enslave us all. Your best bet is to leave out the human part, and go with cheetah/shark hybrids.]
Stranded, Declan and his friends dodge swarms of mythical Egyptian beasts, from a rampaging Sphinx to the jackal-like Anubis. When his friends fall into Ra’s clutches, Declan embarks on a daring gambit. To rescue them and stop Ra’s murderous crusade, he must reach a failsafe device that can destroy the hybrids in one fell swoop. But first, he’ll need to brave explosive geysers, dizzying mountain heights, and crossbow-armed monsters. All of a sudden, those boring moose don’t sound half-bad. [Also all of a sudden, Declan realizes he can always find new friends.]
MONSTER GODS is a middle grade adventure, complete at 49,000 words. It blends the mythological focus of the Rick Riordan Presents series with the action of Laura Martin’s Edge of Extinction. I have my Honors degree in English Language and Literature. [Unfortunately, that will not influence the reader of your query any more than it will influence anyone you contact in your future job search.] Thank you for your time and consideration.
Notes
This is an improvement. Most of my comments focus on whether the reader will buy into the plot.
Wouldn't it have been easier for the hybrids' creators to use the failsafe device to destroy the hybrids in one fell swoop, than to banish them to a place no one knew existed?
Adding the friends helps, but only until they get captured and Declan now has to save them along with stopping Ra’s murderous crusade. Maybe leave out their capture and tell us how they aid the mission.
Apparently Ra is unaware of how much the population and weaponry have advanced while he was in cold storage. Otherwise he'd probably shoot a bit lower than enslavement of humanity. Like, enslavement of Delaware.
