The official bio:"Anna Katherine has traveled the world, and several parallel ones as well, and has discovered nothing is more awesome than duct tape. She currently splits her time between Massachusetts and Maryland."Okay, really:"Anna Katherine is the pseudonym for two women who have both worked in the publishing industry for most of their lives. They started writing the Door-world series -- the first book of which is SALT AND SILVER, now joined by BLOOD AND SALT -- to be a jolly romp, starring a type of heroine they love but rarely see in romance novels."Anna and Kat are both big magic nerds. Anna likes to say that this is the first time she's ever used her college degree in religious studies, and that might very well be true. Kat gives a shoutout to her folklore and Greco-Roman magic studies, which gave her a huge library and a lot of ideas. Both of them have a fondness for French despite neither of them speaking it."
