This is my first book by Wiliams and am now wondering if this is typical of her novels. Should I try any others?

I enjoyed the history in this, which is why it's getting two stars rather than one. I should be able to say this is a character driven novel given its disjointed timeline and rather open ending, but I can't because the characters are not developed well. They never became more than caricatures to me. This resulted in me being bored and thinking the novel was too long and could've been better edited.
