Books like the cherub series

CHERUB () is a series of teenage spy novels written by English author Robert Muchamore, focusing around a division of the British Security Service called CHERUB, which employs children, predominantly orphans, under the age of 17, as intelligence agents.

Initially, the series follows James Choke, better known as James Adams (his adopted name at CHERUB), as he enters CHERUB and performs various missions. However, the focus later expands to other characters, such as James' sister Lauren and several other characters who work alongside him and in separate missions. The initial series of twelve novels runs from the recruitment of Adams to his retirement from CHERUB at age seventeen. The second series of five novels, Aramov, follows Ryan Sharma, another CHERUB agent; James Adams is re-introduced into the series as a CHERUB staff member.
