A Land without Magic by Stephen Elboz
This is the second in a series of books about Kit Stixby and his friend, Prince Henry, which started with "A Handful of Magic". The evil Stafford Sparks has escaped from prison, and he's coming after Kit. Kit must flee the country, and so decides to go with his friend, Prince Henry, to the tiny country of Callalabasa. But will he be any safer here where enchantment is banished and the Knights of the League Against Magic are plotting to destroy the country?
