I'm glad you're enjoying it, Rose--I loved that book way beyond reason, and I'm dying for the sequel as well.
I, um, held my nose through the first two Deborah Harkness books and simply couldn't bring myself to read the third, Kell. And I thought The Goblin Emperor was awesome. Haven't read The Queen of the Tearling yet, but it's on my Nook and my son really liked it.
And is anyone else eagerly awaiting the sequel to The Rook, which comes out in June?
