The dreaded Synopsis

I am 67k words in & have finally bitten the bullet and set about writing the 'Synopsis'.

To me, to congeal the breadth of the story & all its layers down to a few sentences has proven even more daunting than the actual writing of the novel itself.

But I did it. I locked one in. I am not married to it however & will happily accept feedback.

My concerns are:
Q: Does it try to say too much? Not say enough?
Q: Are there too many novel-specific terms included or do they seem defined enough in the Synopsis to let them remain?
Q: My novel is written in 1st Person - Past Tense. I defaulted to 3rd person - past tense for the Synopsis. I'm wondering if it would exude more strength if written from a different POV?

Thoughts?
