What if society wasn't fundamentally rational, but was motivated by insanity? This thought sets Jon Ronson on an utterly compelling adventure into the world of madness.

Along the way, Jon meets psychopaths, those whose lives have been touched by madness and those whose job it is to diagnose it, including the influential psychologist who developed the Psychopath Test, from whom Jon learns the art of psychopath-spotting. A skill which seemingly reveals that madness could indeed be at the heart of everything . . .

Combining Jon Ronson's trademark humour, charm and investigative incision, The Psychopath Test is both entertaining and honest, unearthing dangerous truths and asking serious questions about how we define normality in a world where we are increasingly judged by our maddest edges.

Does the thought of delivering a presentation make your heart skip a beat? Do your pitches fall flat no matter how much preparation you put in? Are you often comparing yourself to more eloquent speakers and wondering how they capture the room?

At some point in our careers we will need to speak in front of an audience; whether to present our ideas to a group of five in a meeting, pitch for investment in front of a panel or deliver a keynote speech to one thousand delegates. Yet glossophobia, or the fear of public speaking, is incredibly common and can inhibit our chances of career progression by up to 15%.

In Speaking with Confidence, Expert and managing director of Speakers' Corner Nick Gold, shows how anyone can learn to be a confident public speaker and use their surroundings to give them the support and structure they need to achieve maximum impact and success from their speech. His decades of experience coaching and producing some of the best speakers in the country have been condensed here into one expert guide to help you connect with your audience every time.

'So clear and true ... Helpful for all relationships in life, not just parent-child' Nigella Lawson

Every parent wants their child to be happy and every parent wants to avoid screwing them up. But how do you achieve that?

In this absorbing, clever and funny book, renowned psychotherapist Philippa Perry tells us what really matters and what behaviour it is important to avoid - the vital dos and don'ts of parenting.

Instead of mapping out the 'perfect' plan, Perry offers a big-picture look at the elements that lead to good parent-child relationships. This refreshing, judgement-free book will help you to:

· Understand how your own upbringing may affect your parenting
· Accept that you will make mistakes and learn what you can do about them
· Break negative cycles and patterns
· Handle your own and your child's feelings
· Understand what different behaviours communicate

Full of sage and sane advice, this is the book that every parent will want to read and every child will wish their parents had.
