Help a newbie: how do I expand the synopsis?

I've just got a Kobo. I've loaded a dozen books into it for my wife.

How do I expand the synopsis? She wants to choose what to read!

I:

1. Hold down a finger on the book title in "my books"
2. Chose "view details"
3. Choose "synopsis"

But then what? Every synopsis is cut short and ends in an ellipsis. How do I expand them out?

Thanks in advance.
