Tilly & Milo prepare for a final showdown with the Alchesmist. Horatio is trapped in an enchanted sleep so this leaves Milo to live his own adventure. This journey leads Milo and friends to the Treehouse library - home of the Botanist, enemy of the Alchemist.
They journey in to some classic children‘s books looking for clues to help them prepare to battle with the Alchemist. I still love the idea of book wandering and travelling to magical places
