Dorie is half human/half fey but she's been trying to put her fey side away for years. Now that she's trying to get a job at Queen's Lab for field work to study wyverns and basilisks. The only problem is that noone wants to hire a woman so it forces her to use her fey powers to change into a man, Dorian. While starting work for Queen's Lab, she discovers the horrible truth about why wyrens' eggs are so popular and why every single person wants them. Now that she has her cousin Tam on her side (who still doesn't know that she is his cousin), they will try to help ironskins, people who were the victims in Human vs. Fey battle that ended years ago.
A lot of reviews that I've read said that it is important that you read first two books. Well I didn't do that and think that I was still keeping up with the story. This is why I really liked it because you can still see how amazing Dorie is. She knows that because of her fey side, she has the stunning looks but she doesn't care about that. She doesn't want people to look at her and think she's only a subject. She wants to be out on the field to actually study and work. The book is a little on the slow pace but it is still entertaining. Plus, the author manages to create a perfect steampunk world with just elements of fey that do play a big role but also keep the reader in the reality.
