"I'm sorry" is one of the hardest things to know how to say. This lovely, sensitive picture book can help show kids the power of these two simple words.

Having a best friend makes life so much better. But even best friends fight, and when that happens, "I'm sorry" can feel impossible to say.

From internationally acclaimed author Sam McBratney and award-winning illustrator Jennifer Eachus comes a emotionally attuned picture book that will strike a chord with every child who has quarreled with a friend. (Works for adults as well!)

Sam McBratney is the author of many popular and incisive picture books, including the classic Guess How Much I Love You.
