Samantha Laing and Karen Greaves have written several books on agile/scrum events. Maybe not always as prescribed by Scrum but very readable, insightful and affordable.
A workshop is probably something you should consider: the Scrum.org classes but also the ICAgile's "Team Facilitation" workshops. Always check if the trainer is certified by Scrum.org or ICAgile. Reading a book about it can help a lot but facilitation is something you would want to see in practice.
