## Summary * Use single unified cache file for book spine, table of contents, and core metadata (title, author, cover image) * Use new temp item store file in OPF parsing to store items to be rescaned when parsing spine * This avoids us holding these items in memory * Use new toc.bin.tmp and spine.bin.tmp to build out partial toc / spine data as part of parsing content.opf and the NCX file * These files are re-read multiple times to ultimately build book.bin ## Additional Context * Spec for file format included below as an image * This should help with: * #10 * #60 * #99
