Caitlyn Sinclair hides her magical need for souls behind her job as an assassin in the Miscreants Guild—the home of spies, thieves and assassins. She is a SoulEater, a mage who uses the aural energy of other people to fuel her spells. She has no choice but to take those lives, because without the infusion of life-force she will die. She's made a home for herself in the city of Ellemarlene, until the day she executes her Guild Master and is cast out. Her only chance at survival is to join the Mage Guild and embrace her magical nature. To become a terrible weapon, someone with the power to wipeout entire towns.
Assassin's Soul begins with us meeting Caitlyn and seeing some of her life. She's an assassin Miscreants Guild, but she's also something more, somethings secret. And when she has to do an unthinkable task, things change far more than she ever what have realized. Now, she must go to the Mages, and see where life take she. Caitlyn's must find a way to survive on her own if she wants to make it through this with her sanity still intact.
This book just wasn't for me. I really didn't like either of the main characters. And I really hated what Caitlyn's friend/lover did to her. It didn't make a lot of sense to me, and I felt like it was pretty unforgivable. So, that just made me dislike it.
Then the ending was rather abrupt, and I felt that some of the things that happened just happened too quickly and not enough consequences for the people who hurt Caitlyn.
Other than that I liked the idea of the story line. I really enjoyed the Soul-Eater aspect of it. And I wish I could have liked more about the story as well.
