 Excellent follow up in a great series. It was even better than the first one and I like the development of characters especially Amos as he's an intriguing and engaging main character. Rest of the team grew on me as well and I sincerely hope Melvin returns in the future books. All the characters worked well together and the plot was interesting. 
 Looking forward to more of Amos and the team!
