Calista Green

This is marketed as a stand-alone novel but if you want to get the most out of it, you'd read the 9 before it and 2 after. This follows the story of cally cross, codename calista green. calista green is a graduate of spy high. This book starts several years after they have graduated (their training is in books 1-6 or series one)and several weeks after her boyfriend, fellow agent benjamin stanton's death. As she investigates the attempted murder of a young genius, she comes to startling revelations about her boyfriends death, the young "victim"she is protecting, and her own past. This is my favorite book series ever, but i fear this is the weakest book in the series. Our main character seems a bit inconsistent. In the first books her main storyline was her becoming more confident and it is all shattered by bens death. she becomes interested in another guy a few weeks later and has a good cry about how she doesnt want ben to hate her. *spoiler* then she finds out he isnt dead and falls in love with him all over again. she just seemed a bit too dependent on him. overall, i recommend the series as a whole but if you want a stand alone read, get edward red or agent orange also by aj butcherand based in the spy high universe.
