Castaways of the Flying Dutchman. He wrote two others in that series. I think one of them was called "Voyage of the Slaves" and the other was called "The Angle's Command"
I haven't read the Legend of Luke yet cause my library doesn't have it. Maybe I'll find it at a thrift store or something. one thing I'm confused about tho, I always thought "Skipper of otters" was one specific character, but he's alive wayyyyy to long. So I was wondering if it was a title for their chieftain like Logolog. Skipper is so many of the books when everyone else is dead.
Lol.
My head-scratcher is that in one book, Diggum is a mole maid, and in the next, Diggum is referred to as "He" while being foremole.
Also as I was reading the books, I was like, "Cregga Badgermum is STILL ALIVE?
I was kind of relieved when she got kind of bumped off in the final book she was in.
