restricted title

[Khushi Kaushik]

 Hi
I wanted to downloade 'Becoming' by Michelle Obama and 'a tree grows in Brooklyn' by Betty Smith. bookshare shows ""This is a restricted title. Either it is not available in your region, or your address information is incomplete"." this is very confusing. I live in India and all my information is complete. I signed up for bookshare because it had more titles available to Indian users as compared to services like audible. these are popular books so I really don't know how they might not be available in my country.
I don't know why am I facing this issue.
I'm looking forward to any answer from the bookshare team.
thank you.
