The arrival of Maxwell the Labrador in Nicky Campbell's life 12 years ago was a major turning point. Ever since the death of his beloved dog Candy, he'd craved the unique companionship that had so enriched his childhood. Co-presenter of ITV's Long Lost Family, reuniting parents with children, as an adopted child himself Nicky knows all too well the tangled emotions and inner conflicts that go with being given up by your birth mother. It has taken a lifetime - and a miracle dog - to come to terms with abandonment and the feeling of being an imposter in your own life. Raw, honest and courageous in One of the Family, Nicky opens up about how being adopted has made him always feel like an outsider; the guilt he has carried towards his Mum and Dad for needing to trace his birth mother, and the crushing disappointment he felt when he finally met her. And for the first time, he writes about his emotional breakdown and how he has learned to live with a late diagnosis of bipolar. Through it all his passion for dogs and animals has been a lifeline. It is Maxwell's magic, a lesson from a Labrador in simple unconditional friendship, that has allowed him to see all the good in his life: from the security and safety of his childhood home, the love of his wife and four daughters and above all, to better understand the decisions taken by his birth mother to give him up for adoption.
