Stop at one, or none
The first book was interesting, if a bit slow and anticlimactic. This second book is just absurd. Glass and his crew are supposed to be fantastic at infiltrating criminal gangs but I truly think they're more like five year olds. The plot is silly, they're unprofessional and make ridiculous mistakes. There might as well be nothing new in this book about India's magic because what we do learn is minuscule and really gives any further understanding of the magic in this world. I'm so frustrated I read this, I didn't realize until I'd already read a free copy of the first book that this is an author who writes series with a slew of books in them in which hardly anything happens, just to eek out as much money as they can.
If you've read the first and know like everyone knows, that Steele and Glass are going to get together, know that by the end of book two, it's still just angsty crap, with her liking him but denying to herself that he's actually looking at her like he's attracted to her. This book left me feeling annoyed, frustrated and had.
