MY reading book 'the killing'

Hello all,
At the moment i am reading a novel called 'the killing' written by Robert Muchamore and it is in the cherub series. The cherub series is about an undercover agency which involves kids aged between 8-18 who have no parents. As I said before Cherub is an undercover agency, so you can't just enroll in this accademy, some cherub kids go to foster homes in mission to find more students for the school because kids in foster homes have no parent. The book I am reading is as i said 'the killing' and i am not very syre what it is really about because i just started reading it, it is number 4 in the cherub series.
