Juvenile delinquent and budding pyromaniac Max Segredo belongs in juvie hall. At least, that's what his most recent foster family would tell you. Instead, Max ends up on the doorstep of Merry Sunshine Orphanage-their very heavily guarded doorstep. As he begins to acclimate to his new home, Max learns a few things straightaway: first, cracking a Caesar Cipher isn't as hard as it seems; second, never sass your instructor if she's also holding throwing knives; and third, he may not be an orphan after all. Soon, Max and the rest of the students are sent on a mission to keep a dangerous weapon out of the hands of LOTUS, an international group bent on world domination. Of course, all Max cares about is finding out more about his father, the man he's now sure is still alive. As the stakes get higher, Max must make some difficult choices, including who to trust, and finally learns the true meaning of family.
