This was my favorite story in the collection! I wish it would have been put first. Yes, there are the formulaic sex scenes toward the end, but at least I was more emotionally invested in the characters and cared about their intimate relationship. This is the first book in the Seasons of Invention Series, Broken Promises is #2. The spy premise is what hooked me and I will be reading the next story to see what becomes of Jasper and Callie. In comparison, the kick off to this series reminds me a little of Lauren Willig's Pink Carnation series, but with a Steampunk edge. Readers who like Gail Carriger's Parasol Protectorate series will likely enjoy this one too. Tension, suspense, action, romance...it does have it all.
