If you've ever had a good idea and wondered, Now where did that come from? then this book is for you. It tells how all ideas are mined in a parallel world before magically being released for our discovery. The year is 1750. A lonely boy named Joey stumbles into this parallel world behind his family's farmhouse and is elated to find his old friend Ben there. Together they join an expedition to retrieve a gusher-a buoyant, glowing sphere that holds an as-yet unthought-of brilliant idea. With a crack team of finders, diggers, seers, and winders, they face bloodthirsty trolls, an insane miner, and unrelenting hardships on their quest.
