A new urban fantasy series featuring a girl who finds herself with magic she never new she had and dealing with working with her ex best friend who might have created something that could destroy the world. Petra Grady is a Sweeper first class, she is tasked with cleaning up mage's spells and dross, the damaging, magical waste made from mage's spells. Sweepers are considered as second-class but Petra is an extremely talented one. When she is forced to work with Benedict Storm, her childhood friend turned nemesis who broke her heart and destroyed their friendship, she is not excited. Benedict is working on research that could render the Mages' dross inactive and make Sweepers obsolete. Petra knows this is an impossible task and that whatever Benedict is doing is going to end up being dangerous and a failure, yet her team wants her on the project to oversee what is happening and give them insight. Benedict doesn't understand dross the way Petra does and strange things are happening around Petra, from her roommate acting weird to her neighbor being around her more... not to mention the fact that Petra might have to finally get out of her own shadow and reveal her talents... which could shatter the world. This book is the first book in a series and unfortunately I don't think I will be continuing on with this series. The book had an interesting world at first but then I found myself disliking the characters and not at all caring about what happened to them or the world. The magic system was unique and I liked the urban fantasy setting. I however, did not like Petra at all. Petra made terrible decisions that had me frustrated and honestly I couldn't care less about the other characters and what they were doing. It felt like a drag trying to get to the end of the book and I so badly wanted to DNF it many times but kept pushing myself to finish in hopes that maybe it would get better (spoiler: it did not). I feel that if you like slow moving urban fantasy novels with a pretty naive and young protagonist and no romance, give this one a go, maybe you'll have a better time with it than I did.
