The Patronus spellbook is a book with instructions and information on the Patronus Charm, owned by Remus Lupin.[1]
History
Lupin used it during one of his Anti-Dementor lessons with Harry Potter. He placed the spellbook within a secret passageway accessed through the cupboard in Professor Cuthbert Binns's History of Magic classroom, and put a Boggart there also, knowing it would take the form of a Dementor, Harry's worst fear. Harry took the book with him and learned how to perform the incredibly advanced and powerful protective charm, and presumably gave it back to Lupin afterwards.[1]
