Another Day in Paradise by Eddie Little
When Bobbie meets Mel he' 14, a 'very fucked-up kid', shooting speed, eating pills, surviving by robbing vending machines, petty burglaries,stealing stereos out of cars...Mel knows things - like how to crack a safe, the best way to set up bogus checking accounts, the fine art of cutting through walls and ceilings - he teaches Bobbie not only how to survive, but how to actually thrive. As Bobbie says, it's 'kinda like Jesuit training for thieves'.
