Summary: Sie lernen sich in einem Chatroom kennen und wollen es erst nicht glauben: Alle drei wurden künstlich gezeugt. Merit, 17, weil ihre Mutter in einer lesbischen Beziehung lebt. Frederick, 15, weil sein Vater unfruchtbar ist. Dennis, 15, weil seine gehörlose Mutter ein gehörloses Kind haben wollte. Sie könnten unterschiedlicher nicht sein, doch in einem sind sie sich einig: Sie möchten wissen, wer ihre leiblichen Väter sind.

Summary: A mix of gripping story with fascinating facts on left-handedness. Everyone should think left-handed - or so 14 year old Jamie thought when she tied her hand behind her back for a day-long protest in school, against persecution of left-handers over the centuries. Her best friend Ryan publicised their cause with a new series of articles in the school magazine but just when their campaign is going well, Ryan's Mum drags him off from Wales to live in America. There he faces bullying at its most deadly and Jamie has to live from one email to the next to know whether her friend is coping.
