This book is one in a series about the friends Ernest, a big bear, and Celestine, a little mouse. They may appear an unlikely pair, but their friendship is strong.

When Celestine breaks a cup at breakfast, who clears up the pieces? She may be small, but Celestine has heaps of determination.

An animated movie of Ernest and Celestine was made in 2012.

Gabrielle Vincent was a pseudonym of Monique Martin, a Belgian writer and illustrator born in 1928.
