Digman!

While searching for Amelia Earhart's plane, Rip and the gang find themselves taken aboard a floating airship in the sky, where Swooper finds a great new opportunity; Agatha finds romance; Rip and Saltine find a lot of trouble.

Rip goes on an undercover mission to find a long-lost sonnet from Shakespeare's legendary oeuvre, but things get sticky when he crosses paths with a charming thespian.

Rip journeys to the distant Puffland in pursuit of the Holy Grail to resurrect his late wife Bella, but his solo mission goes awry when the king arranges for Rip to marry his daughter.

It's the Grand Opening of Quail Eegan's new museum — and Rip Digman will stop at nothing to infiltrate it. Meanwhile, Saltine must delve into the seedy underbelly of the Arky world in order to learn the truth about a dangerous artefact.
