Abigail Rook has a job as an assistant to free-lance detective Jackaby. Jackaby has a rare gift as a seer. He can see magical residue and detect magical creatures that are otherwise invisible. Jackaby and Miss Rook are called out to the country to investigate a murder at a dig site where some kind of prehistoric bones have been discovered. Miss Rook is eager to visit the country, since her friend Charlie has been stationed there as a policeman, but she wonders if she can balance her career and romance.

I loved this book so much! I really liked the world-building and the way that the supernatural creatures mingle with ordinary humans. Even the most wild magical theories end up having some supernatural explanation.

I especially loved Jackaby and Miss Rook and their detective partnership. They are both full of witty remarks and flippant little quips. Utterly delightful!

I loved Miss Rook's character! She is very introspective, analyzing the clues and analyzing her relationships with people. We get to see her emotional turmoil as she tries to adjust to her new adventurous life. She goes on quite an inner journey to find the confidence to trust herself and make her own decisions for her own life. She is so spunky!

The writing style is excellent. The plot is mysterious and fun! The mystery really kept me guessing, and I loved all the strange clues. Because there are magical elements in play, it's difficult to tell what is just a normal clue or what is some weird supernatural power at work. There are a lot of moving parts in the plot, and characters with different abilities and secret knowledge. It becomes like this weird game of chess with red herrings all over the place, until you realize that the red herrings are actually the center of the mystery. Such great plot twists!
