In Book 2 Chapter 10 "The Library".
book three is the last book of avatar though, some comment by the editors suggest that new series with different characters. they have to make a 4th season because we still new to find out wat happens with toph and her family, katara and aang and we need to find out about zuko's mother. they have made a short vidieo which is just a joke vidieo but its called Forbidden Love and if there is a forth season this may be the first chapter of it
