Meh. Meh meh meh. Teenage romance is boring. Forced historical misogyny is very hard to do well, and it was not done well here. There was a massive leap between the clues and the eventual culmination of the mystery that really didn't follow. The horse stuff was very wrong (a terrifyingly tall stallion is probably not an Arabian. A horse is probably not going to respond to a friendly stroke on the flank with 'an affectionate whinny'.) The anatomy/medical history stuff was quite good (author's note cites Lindsey Fitzharris's excellent 'The Butchering Art' and Eleanor Herman's delightful 'The Royal Art of Poison', among others that I should probably track down, given the recommendation that springs from their association with their fellow citations.) Apparently there's a sequel coming out next year, and while I'm very happy for Dana Schwartz, I have no intention of reading it.
