A glitch becomes a crisis
Strange gravity, flickering landscapes and a gathering Rift turn a familiar game into an urgent journey. The boys need to reach their unfinished rocket in Junktopia if they hope to get home.
A spoiler-light look inside
When the creators become part of the adventure.
Eli and Cain’s virtual world is full of talking mice, floating islands and wonderfully unpredictable inventions. But when one of their creations begins to behave in unexpected ways, the boys are swept into the Miceverse themselves. Their playful project has become a place they must navigate for real.
A world of changing rules
From the bright, candy-coloured Pink Planet to the floating Nimbus Isles and the tangled greenery of Emerald Island, every part of the Pentapelagos brings new surprises.
Imagination carries responsibility
Along the way, Eli and Cain meet mice who need their help and face problems their inventions cannot simply fix. Their choices matter to the world they created—and to each other.
