Think about your hook... if you had to choose four words for my eye to fall on in the first sentence, what would they be?
I'd hazard to guess "fourteen boy special powers"
It's probably not "Living orphanage Rome fourteen". That "Grab" is for a very different book, probably closer to Les Misérables.
Once you have your key terms, try to topload them if you can.
These things are always easier to see in other people's writings, so he's a sample for VQS:
Regular wrote:Travelling amongst various monasteries, Shinji, the son of an accountant, loses his Sensei on planet Venus. He must apply his skill with the sword to survive a hostile and alien world.
top-loaded wrote:Thrust onto a hostile and alien world, Shinji must use every combat skill he can to survive. He's lost his Sensei. He's but the son of an accountant. How can he survive?
(Actually, that can be much more top-loaded, but that's a whole different topic)
