September 2, 2026: We are upgrading! While we prepare for our new Paired for Progress bundles (50 books, 50 booklets and an Educator Guide), we are temporarily pausing book orders for the next few weeks. Our team is currently hard at work behind the scenes upgrading our systems (read: inventory software, box tetris, computer thingys and advanced MATH). We will reopen ordering as soon as we have our packaging & inventory squared away and our new bundles are ready for order. We appreciate your patience. [Booklets, magnets and sample kits are still available.]
