I LOVED this. I love the trope where the main character is either really bad at magic or has none and I thought the whole concept of magic releasing dross which breaks into bad luck was so unique and interesting. Petra was such a fun character to read about and follow along on her adventure. I appreciate how she didn't let her feelings for Benedict make her lenient towards his experimental process that she didn't agree with. She stuck very strongly to her personal opinion and made the decisions that were best for everyone and not just for Benedict because she liked him. I wish I could say I saw the plot twist with Ashley coming. I was a little suspicious when she was having secret conversation with her 'career counsellor' but I was totally took of guard to find out she was a rebel. I never like when books kill dogs and I did take of 0.5 stars because if poor Pluck but Petra's ability to control shadows and her personal shadow companion taking the place of Pluck made things a little bit more okay. I loved how she got to learn the truth about her father and Herm and I appreciate how she forgave him after years of resentment and hatred. I loved the decision to work with the mages to take down the rebels and how the shadows came to her protection and took down the rebels for her. I loved her and Benedict's relationship and how it grew and they came to terms with their differences and began to see things for the other person's perspective. I cannot wait for the next one cause this book was incredible.
