The boy, the mole, the fox and the horse by Charlie Mackesy

If at first you don't succeed, have some cake.

They also made a movie from it for those who hate books.

It's one of those children’s books that I recommend to adults.

It’s about appreciation, about curiosity, about adventure, about love.
It's about kindness, about beauty, about fears and about fun.
It's about everything that truly matters in life.

It's how I used to see life as a child, but gradually forgot as I grew up into an adult.

It's short, sweet, and lovely. It's like a warm hug in a cold, lonely winter night.
