My thoughts are in blue, words to delete are in red, suggested rephrasing is in orange.

I seek representation for my 96,000-word literary fiction manuscript, A Children’s Playground. I always tell people not to open with your word count, title, or the fact that you're seeking rep - they know that, you're querying them. Everyone else querying also has a word count and a title. Start with what only your have - your hook.

In the wake of the Global War on Terror, Unfortunately, this could span a pretty large amount of time, so you might want to be a little more specific. twenty-four-year-old Asad Khan, an Afghan tribal heir, and twenty-three-year-old Anna, a once-promising American music prodigy, find their lives intertwined, weaving a tale of resilience, love, and sacrifice as they search for a common future across two nations in conflict. This is a great intro! Definitely lead with this. After reviewing the entire query, however, this opening makes it sound as if Anna will be sharing half of the narrative, but it doesn't really look that way. She's a factor in Asad's story, by the way the rest of this query reads.

Straddling the responsibilities of succeeding his aging father, a war hero from the Soviet-Afghan war, as the new tribal chief and his dreams of becoming a successful Silicon Valley entrepreneur, an agonizing revelation shakes Asad to the core: an American drone strike in his remote village along the Afghan border has brutally injured his childhood playmate, Samina, ultimately claiming her life and that of her family. This paragraph is basically one sentence, so you need to break it down. I highlighted spaces above where it's getty wordy and some things can go. Also, if Samina ultimately dies, I'd just say that she's killed, along with her family.

This jarring news ignites inner turmoil as Asad strives to reconcile his affection for Anna and his newfound home in the USA with his duty to address the ravages of war against his tribal brethren. In this soul-searching tussle, Asad loses Anna not once but twice. Anna needs more room here. She's got a brief intro in the opening para, but she's not being built here at all other than a shadow of a real person. How serious is "affection?" What is the nature of their relationship? What is he losing if he loses her? Also, the vague nature of loses Anna not once but twice doesn't work in a query. Lost her how? Gained her back how? Lost her again how? How is any of it tied to his inner turmoil?

Will Asad choose love and a life in the USA with Anna, or honor family expectations, returning home to avenge Samina’s death and lead his tribe against the New World Order, risking everything to save his homeland from destruction? Don't end with a rhetorical question, that's not a good way to round things off. Instead phrase this as him facing a choice, and illustrating what he loses or gains either way.

A Children’s Playground echoes the timeless themes of social upheaval caused by war like Khaled Hosseini’s The Kite Runner with the identity struggles of Mohsin Hamid’s Reluctant Fundamentalist in the clash between East and West.

I was born in Karachi, Pakistan. Currently, I live in San Jose, California. I served as a military pilot and lived in seven countries. I have endeavored to capture this interplay of human diversity and conflict to provide the readers with both sides of the story in my debut novel, answering the age-old question: Why do kind-hearted, well-meaning people worldwide find themselves entangled in wars so frequently? If you don't mind me saying so, as a non-military person that lives in the US, I don't find myself entangled in wars frequently. I think this is distinct to areas of the world and certainly sets up a great question in regards to Anna - could she ever understand that mode of living?

Overall your query is well-written, but we need a little more plot detail in here. The overall question - what will a man torn between two cultures choose? - is very clear, but the more granular aspects of the plot aren't present. A divided life is a known narrative - what makes yours distinct and separate from the others? Get it into the query.
