I read an interesting post today about atypical story arcs, by Joyce Audy Zarins. Instead of the usual rise and fall (pictured above), some story arcs take on less traditional patterns, like the "X" shape arc in Bridge to Terabithia where Jesse and Leslie switch roles by the end.
Joyce also mentioned the cyclical arc of Holes, by Louis Sachar, and how fitting that is to the title and development of the main character.
I started looking around for other ideas about arcs and ran across a lecture by Brandon Sanderson. He briefly talks about non-traditional arcs but then answers a student's question about collaboration, also an interesting topic and pertinent to a discussion on arcs.
I'm also churning away at my middle grade novel and revising a handful of picture book ideas I think have the most potential. Between all that, I'm organizing a children's lit group in my new home as I did in my previous home. There is no SCBWI chapter here, but I'm trying to lay the ground work for establishing one. It's been a busy but fruitful transition. Hopefully I'll have more good news to share in the near future.
