This is quite a sad book.
To read it as an adult had me close to tears. That Barnaby's parents could be so awful, could resent him so much...
But if I'd read this as a child I think it would have been a wonderful adventure. To float, to go anywhere, to inadvertently travel the world and meet so many different characters, it would have been wonderful.
This book teaches some great lessons - the most important are that it's not wrong to be different and that everyone has their own definition of normal. It's OK to be gay, to have a crappy job, to be horrifically scarred, to be a freak.
I won this via Goodreads First Reads.
