The fun continues. My brother and I disagree about both Miriam and Roland. I think it isn't quite believable that Miriam makes the perfect technology choices outside of her wheelhouse, biotechnology. My brother, a freelance journalist, thinks it is credible. He thinks Roland is out of a romance novel. I think he has been in DC too long.
Olga and Brill continue becoming more interesting; they make a wonderful foil for how emotionally clueless Miriam can be. Her mother's emotional relationships were a pleasant surprise and I found the end really sad.
