Greaves is charged with violating florida's obscenity law.
Florida authorities contend Greaves sold and mailed his book to undercover Polk County sheriff's deputies, and even signed it for them.
The book - "The Pedophile's Guide to Love and Pleasure: a Child-lover's Code of Conduct" - caused a flap when it showed up on Amazon in November. The self-published book was later removed from the site.
Greaves, who has no criminal record, writes in the book that pedophiles are misunderstood, as the word literally means to love a child. He adds that it is only a crime to act on sexual impulses toward children, and offers advice that purportedly allows pedophiles to abide by the law.
