Cherub

I love the series of books called Cherub. It is a fiction novel about two kids named James and Lauren going to a school that trains you to be a spy like completing a 100 day of tough training, martial arts, know how to use weapons, and etc...
They go on different mission to stop people in the world doing bad and illegal things. I love all kinds of spy books like Alex Rider, Bodyguard and etc...
Those are also the books that I would recommend to people who has the same interest as me.
