Sir Duston and the Marble of Light (en Inglés) - Landis;Rein G.

Beneath the quiet stillness of a child's bedroom lies a hidden world: an underbed kingdom built of lint and crumbs. When the kingdom's most precious treasure, the Marble of Light, mysteriously vanishes, darkness begins to creep in, threatening not just their home, but their hope. In the midst of panic, an unlikely hero emerges: Sir Duston, a small, gentle dust bunny who has never seen himself as brave. Chosen to lead the search, he must journey beyond the safety of his world - through towering sock mountains and past forgotten toys - to find the marble before the last bit of light is gone forever.

"His underbed, dust bunny realm is creative and compelling - a cross between Toy Story and The Steadfast Tin Soldier. Character names mimic those found in Chronicles of Narnia, adding a unique twist of suspense and curiosity." - Meagan Clements, author and credentialed school teacher
