Made with care.
Built for curious families.
Books and logbooks designed to help children notice the world, ask big questions, and remember every journey.
Two brands, one home. Both made for families who love to explore.
Travel logbooks designed for kids of all ages, covering every kind of adventure — flights, cruises, road trips and train journeys. Created by a former cabin crew who spent twelve years in the skies with Air Nostrum, Emirates and in private VIP aviation, and now travels the world with her two children by air, sea, road and train. Adventuring was born from a passion she carried long before motherhood and passed on to her children since birth.
A picture book series for children aged 3 to 6, built around one simple question: why? Millie and Alphie are joined by gentle animal guides who help them explore the big questions children ask every day — about dreams, thunderstorms, friendship, and everything in between.
"We are the Why Club. Ask a why and we'll try."

Twelve years in the skies. A lifetime of curiosity. Two children who never stop asking why.
Rocío Dos Santos Arenas
I spent twelve years as cabin crew — with Air Nostrum, Emirates, and in private VIP aviation — traveling the world with a notebook and a curiosity I could never quite switch off. Every destination, every flight, every journey left something worth remembering. I wanted to hold onto all of it.
Adventuring was not something I invented after becoming a mother. It was a passion I carried long before my children arrived, and one I placed in their hands from the very beginning. Both of them have had their own logbooks since birth. The books were always theirs too.
The Why Club came from a bedtime question that did not have a simple answer — the kind children ask when the lights go out and the world suddenly feels very large. I wanted a book that took those questions seriously and answered them with warmth.
