Harry Potter and the Prisoner of Azkaban is my favorite book out of the series. I don't really know why... Maybe because Sirius Black is in it and he's my favorite character and all...
If you haven't read the Harry Potter series then you must! It is the best series everrrrrrrrr!! :)
Many people seem to agree with my opinion. On Amazon.com . . ..
One Amazon.com reader states, " I thought AZKABAN was not only easily the best of three, but one of the best books I had read in a long time."
