The Irregulars, those delinquent Girl Scouts: Kiki, Ananka, Oona, Betty & Iris, are still protecting the secret city that lies beneath Manhatten. Trouble comes from an unlikely insider when it is discovered that Oona’s father is Lester Liu, the New York gangster they are protecting the secret city FROM.
The trouble is, Oona has known this all along and never told the Irregulars. Oona wants to trust that her Dad has turned over a new leaf but the Irregulars are skeptical and hatch a plan to find out what Lester is up to as well as keep an eye on Oona while she is in Lester’s mansion. Illegal immigrants, Russian operatives, an art museum and a Chinese mummy all play a part in the mystery of Lester Liu’s new life. Is he really turning into Daddy of the Year or is this just another plan to line his wealthy pockets? The Irregulars won’t stop until they find out the truth.
