I’m looking for a book,
don’t remember what it’s called;
about a wizard, I think
and the cover was bright blue
or it may have been pink

or have you got that one
about four sisters in the States
at least I think it was the States;
the heroine doesn’t marry the hero
they’re just mates.

If you haven’t got either of those
I like the one about a boy
who doesn’t want to be a man,
too busy fighting pirates,
flying, having fun.

I can’t remember the names
but these were my favourites.
I can’t find them on the shelf
but I’d love to read them all again
if you’re able to help?
