When Niall Minogue's wife, Oonagh, had a stroke at the age of just 36, himself and his kids put their heads together to bring a little bit of positivity to her recovery.
The result is a magic book that can change your life in just 28 days.
'Taking Back My Life 28 Days' is all about focusing on the positive, and reminding yourself of five moments in the day where you smiled, laughed, guffawed or even felt a moment of joy.
During these difficult times, Niall wants people to take a few minutes before bed to write down the good parts of the day-it could be as simple as hearing your kids playing in the back garden to the very cute Labrador you saw on your walk.
Niall joined Dermot and Dave to explain all about the book and how it's already well on its way to being a massive hit.
