The third (and supposedly, final) installment in Rachel Vincent's Unbound series, Oath Bound was one of my most anticipated novels of the year. The unusual, mob-style world and distinctive, yet not overwhelming, paranormal elements have made this series one I've enjoyed immensely, and recommend often.
Fortunately, Oath Bound met my expectations and while I didn't love it as much as the second book in the series, Shadow Bound, it equalled the quality of the gripping first novel, Blood Bound. However, for an alleged final book in a series, I was definitely left feeling that there was quite a bit more needed in order for the series to achieve closure (though as with the previous books, the story itself comes to a satisfying ending).
Note: I have made every attempt to not spoil either of the two previous books in this series. While this novel would be best read after reading Blood Bound and Shadow Bound, it could be read as a standalone.
Here's quick primer on the Unbound world: The best comparison I can make is to Holly Black's Curse Workers series (which I also highly recommend). Some people are Skilled, and are able to utilize their Skills for a specific purpose, such as tracking people with just a name, teleporting via dark spaces, jamming tracking skills, binding contracts in a way that they're unbreakable or seeing future events. Like in the Curse Workers series, these talents are often commandeered by crime families, whose organizations exploit the Skilled for the benefit of their criminal enterprises. These organizations are ruthless, and the particular city these novels take place in are ruled by two rival, ruthless syndicates: Tower and Cavazos.
The Unbound series explores the theme of free will quite extensively, as that's the most valuable commodity in this world.
Each of the books in the Unbound series are told from two first-person points-of-view. In Oath Bound, one of those points-of-view is Kris, the brother of Kori, who was a narrator in Shadow Bound, and Kenley, an important secondary character in both this novel and the previous installment. The other narrator is a new introduction, Sera, who's the secret daughter of Jake Tower, former leader of one of the Tower syndicates.
