4.5 stars. I really enjoyed this book. The worldbuilding and characterization were excellent. The only thing I disliked was that the plot seemed to take a while to get going (it was mostly dialogue in the first half or so without enough action for my tastes). But when the characters started running into each other, things got interesting and the book was difficult to put down. The banter between them--especially assassin Harr and doctor Glyneth--was so entertaining. Dianthus was a truly endearing and fascinating character. I'm looking forward to finding out what happens next.
