I am reading To Green Angel Tower, and just reached the point where Cadrach is with Miriamele and Binabik, in Hayholt's tunnels, and tells them the full story about what Pryrates wanted and how he didn't care about the swords. Miriamele is angry at Cadrach for betraying them, and when Binabik points out that Cadrach didn't know them and he can't be blamed for telling Pryrates information under torture, Miriamele says she's angry because if he had told them the full story about the swords sooner, they would be able to do something.
I don't really understand why Miriamele is angry with Cadrach. Cadrach already told Miriamele, after they escaped Aspitis, that Du Svardenvyrd is an evil book and contains information that no human should know. What I understood from it was that Josua's company should not be trusting this book as a way of fighting Ineluki, and the poems are going to lead them down the wrong path. I kept expecting Miriamele to warn Josua and co, especially when she discovered that Tiamak had a page of the book, but she never did.
Do you think Miriamele was angry with Cadrach partly because she blamed herself for not warning everyone about Du Svardenvyrd when she could, and especially for not letting Cadrach look at Tiamak's page of the book (since if he had, he might have said something)?
