This volume combines two adventures from the beloved Minton series, which follows the escapades of a mischievous, imaginative guinea pig. In Underwater, Minton likely embarks on a whimsical, make-believe journey to the bottom of the sea, while Home at Last concludes a journey, perhaps one that got a bit too big for his tiny self. Anna Fienberg's stories are known for their gentle humor, warmth, and celebration of the power of imagination. The book captures Minton's endearing combination of curiosity and nervousness, making him a highly relatable character for young readers. This combined volume offers double the fun, reinforcing themes of adventure, comfort, and the security of a loving home.
