Being a first book there were certainly some growing pains present. The pacing and plotting felt off. The animosity between Claudel and Brennan felt super forced. That being said, it held my attention throughout. the action largely exist in the last thirty or so pages. Tempe was seriously frustrating in this one. Going off all half-cocked, rushing headlong into dangerous situations with zero planning. 

hopefully there will actually be some development in the next one
