The Sketch Survivors: The Defense of Fort Whal

{Book Two of the Sketch Survivors Trilogy}
After the Rooted Spire burned and Lint Corp betrayed our Un-Characters, they now know the dark side of Lint Corp. The First Brigade has been separated, though- Soal chasing Moth into the flaming Spire, Renyrocrattus taken away to be studied, and the rest of the Brigade taken away by Lint Corp for strange experiments. Through a quick succession of events, Soal joins the Revolutes; a large organization of rebellious Un-Characters who evaded Lint Corp and clashed with them in the Sketch Facility for years. Their leader, the elusive Green Phantom, is intent on reaching Fort Whal in the outskirts of a Sketch called Iminentia before Lint Corp arrives to take back the Un-Characters they lost. She notices Soal quickly, but doesn't take him into account until a harrowing event.
When their legion of Revolutes finally reaches Fort Whal, Lint Corp mounts a serious attack on the fortress. A desperate struggle begins as Soal uncovers Lint Corp's lies and secrets about his past; and a new goal appears in Soal's mind: stop Lint Corp. What from? He doesn't know, but the tension is escalating, and the fate of the Sketch Worlds, the Un-Characters, and Soal's life are all at stake.
