Hard to say. Most 'premium' apps for iPhone are being priced at $1.99-$2.99. Since yours is an iPad first app, you could probably charge $2.99-$3.99. I read so much on my iPhone that I'd gladly pay that much, but I doubt I am typical.
You may find it is more interesting to offer your app for free with an optional in-app purchase ($1.99, let's say) that unlocks certain non-essential but useful features such as: summary creation, deep view, additional themes, increased number of books in library (i.e. maximum of 5-10 titles in your library for unpaid version, unlimited for paid). That approach is having a lot of success lately.
