Why can't I buy Usborne fiction books in the USA?

The majority of Usborne books are written and designed by our in-house team, at our offices in the UK. However, our fiction range is acquired from authors via literary agents. This is a more traditional publishing model, and one which can often lead to rights restrictions - if we are not able to buy US publishing rights from authors' agents, we are not able to distribute those books in the USA. 

We're really sorry for any disappointment caused by this, but it's out of our hands!
