Instagram phenomenon @1bike1world Dean Nicholson reveals the full story of his life-changing friendship with rescue cat Nala and their inspiring adventures together on a bike journey around the world.

When 30-year-old Dean Nicholson set off from Scotland to cycle around the world, his aim was to learn as much as he could about our troubled planet. But he hadn't bargained on the lessons he'd learn from his unlikely companion.

Three months after leaving home, on a remote road in the mountains between Montenegro and Bosnia, he came across an abandoned kitten. Something about the piercing eyes and plaintive meowing of the bedraggled little cat proved irresistible. He couldn't leave her to her fate, so he put her on his bike and then, with the help of local vets, nursed her back to health.

Soon on his travels with the cat he named Nala, they forged an unbreakable bond - both curious, independent, resilient and adventurous. The video of how they met has had 20 million views and their Instagram has grown to almost 750k followers - and still counting!

Experiencing the kindness of strangers, visiting refugee camps, rescuing animals through Europe and Asia, Dean and Nala have already learned that the unexpected can be pretty amazing. Together with Garry Jenkins, writer with James Bowen of the bestselling A Street Cat Named Bob, Dean shares the extraordinary tale of his and Nala's inspiring and heart-warming adventure together.
