Gilbert Hernandez's graphic novel Palomar will be available in the Rio Rancho (New Mexico) High School library when classes resume in the fall, but there's a catch: Students under the age of 18 will have to get a parent's signature before they can check out the book.

Parent Katrina Lopez turned to the local news media in February after her 14-year-old son checked out the mature-readers book, reportedly thinking it might be manga. When Lopez leafed through the pages, she saw images she characterized as "pornographic."

While a school district spokesman initially called the book "clearly inappropriate for students," a committee chosen by the superintendent later voted to keep the book in the library, saying it met the standard of the Rio Rancho School Board’s Library Bill of Rights.

Lopez said at the time she would appeal the decision.

The Comic Book Legal Defense Fund wrote to the school board in March to defend Palomar, and accused the TV station that aired the initial story of biased reporting.
