I would not give it completely 4 stars ( I would say more 3.5 or 3.75). The writing was very good, I learned some minute details that I didn't know before and I definitely plan on reading the continuation of this series. The only reason why I graded it a little lower is because the actual case that was being solved wasn't what I had hoped it would be, but that is just personal preference.

Looking forward to book 2!
