ABANDONED. YA book about boy who learns to fly because he didn’t acknowledge gravity

[Nadiya]

YA book. I remember very little except there were two brothers and one brother was really weird and declared his room a “gravity-free zone” and I think he and his brother played with toy soldiers and the weird brother eventually flies away. Read circa 2010.

Nadiya, is this a fantasy book (or does he learn to fly as an adult pilot)?

[Rainbowheart]

How old are these brothers, teenagers or younger children?

Did the boy grow wings?

The Terrible Thing That Happened to Barnaby Brocket, by John Boyne?

There's nothing unusual about the Brockets. Normal, respectable, and proud of it, they turn up their noses at anyone strange or different. But from the moment Barnaby Brocket comes into the world, it's clear he's anything but ordinary. To his parents’ horror, Barnaby defies the laws of gravity - and floats.

It’s fantasy, no pilots to my knowledge

[Rainbowheart]

Nadiya, did you rule out Robert's suggestion above?
