A sequel to "Pioneers" and "Wings" that began as a roleplay chat. Previously serialized on Scribblehub, this is its first appearance on DeviantArt. It's a collaboration with @styn246 .

This is an epub file; download it using the down-arrow icon on the lower left. I expect DA will rename it as a .zip file like it did with my Trust Machines epub collection a while back, so you'll need to rename it to puzzlebox.epub before importing it into your ebook reader. Note that my previous post was a PDF version of this novel.
