Hope

For the first time I read two books at the same time and found a very interesting topic: hope.
In "I am Number Four" Pittacus Lore writes:

'When you think all is lost, when all is dire and bleak, there is always hope'.

In "Heart's Blood" Julier Marillier writes:

'"Hope is dangerous, Caitrin," he said after a little, his voice calmer. "To allow hope into the heart is to open oneself to bitter disappointment."'

What do you think?
