The Tigress Caged

In the third volume of the Eleanor of Acquitaine novels, Eleanor finds herself torn between her early love for Henry II of England and resistance to his constant bullying of her and her sons in his fear of being superceded by his ambitious offspring.
His paranoia leads him to imprison her to curtail her powers, but this makes her only more determined to resist him and defend her birthright, while, at the same time, reining in her sons' impulses to overthrow him.
Who will win out-the autocratic Henry, or the resourceful Eleanor? It seems time may be on her side...
