Revolting youth - C. D Payne

In the wry and subversive sequel to Youth in Revolt, America's most literate (yet shamelessly crude) teen diarist accidentally ignites criminal mayhem, seeks union with his love, Sheeni Saunders and still has to live as a girl to avoid police detection. But now, Nick has decided that he must marry Sheeni in order to ensure that she is with him forever. In pursuit of this goal, he almost blows his fortune, nearly cripples the nation with a computer virus, shoots his future father-in-law and undergoes radical plastic surgery to resemble a French actor!
