★ Your weakness can be your strength! A warm, healing story about self-acceptance.
★ Set in a "heart repair shop," this episodic tale follows Mr. Gosum as he mends the worries of different visitors. Each standalone story carries its own emotional theme—fear, loss, protection—while weaving together the protagonist's journey of growth.
★ Mr. Gosum, a hedgehog who feels ashamed of his spiky exterior, unexpectedly discovers that his quills can repair broken things and comfort wounded hearts. The story ingeniously transforms "flaws" into "gifts," helping children rediscover their self-worth and learn to embrace their imperfect selves.

Mr. Gose, a hedgehog living alone in the forest, hates his sharp spikes and hides from the world. One day, a small visitor arrives, and soon others follow, each bringing a broken item and a story. Using his spines as a needle, Mr. Gose repairs dolls, ear warmers, eye patches, and more – while listening to the owners’ fears and sorrows. As he mends their belongings, their hearts heal, and Mr. Gose begins to see his spikes not as a curse, but as a gift. A tender tale about self-acceptance and the unexpected power of our differences.
