Anne McCaffery has written a whole series called The Drachen of Pern, it was the first Fantasy book i read and fell in Liebe with Drachen from these books, best Bücher ever.
Dragonology Von Ernest erpel, drake (I think) is very good, but it is Mehr like an encyklopedia, in the sense that it describes different types and so on. However it is very entertaining and has beautiful illustrations. Temeraire series is also very good, it is set in the time of Napolean wars and Drachen exist, so Britain has Royal Air Force of dragons. It is very nicely written, funny at some parts, the universe is well thought out. The series has six Bücher in total I think.
