Figment 2 / Zub, Jim

"Figment, Capri, and Spark search for Dreamfinder in the Doubtfinder's mindscape, but can they survive the experience?"--Amazon.com.

After flying through a portal, Dreamfinder and Figment find themselves in the 21st century at the new Academy, but when a demonstration goes wrong, Dreamfinder transforms into Doubtfinder, leaving Figment and Capri free to find Dreamfinder before doubt can take over the world.
