Hi,
I have "ball pythons" by john coborn - lovely pictures but , as it was published in 1994, the husbandry information has moved on quite a bit. And the morph section compared to modern information will give an idea of how dated it has become.
The two books mentioned above are the best of the best but ,sadly, the prices reflect this. If you just want the correct information for the moment I can highly recomend this book;

By the way you really do want the other two as well- drop a few hints for Christmas and birthdays.
