I recently finished my first Librarians novel, 'The Librarians and the Lost Lamp'.
It was exactly as expected, fluffy, fun and bit mad in places. Just like the TV show. The story focuses on Aladdin's lamp and the race to get it before the forty (thieves) do. It's set in two time frames, 2006 with Flynn Carson back when he was still the sole Librarian, and 2016 with the team from the show. It was a quick fun read and I'd be happy to read more Librarian novels in the future.
