Geronimo Stilton #15 and #16

"The Mona Mousa Code" is an engaging audiobook that follows young detectives as they unravel secrets hidden in Mouse Island's most famous painting, leading them on an adventure beneath the streets of New Mouse City. Meanwhile, another story features a young rodent accompanying her grandfather on a journey to write a guidebook about the remote and chilly Ratzikistan, despite her dislike of traveling. Both tales promise exciting discoveries and lively exploration in a charming rodent world.
