Borders Group is offering exclusively two titles to tie-in to Harry Potter and the Deathly Hallows, using the biggest book of the year to follow through on plans to step up its publishing program.

The Great Snape Debate by Amy Berner, Orson Scott Card and Joyce Millman explores whether Hogwarts professor Severus Snape, one of J.K. Rowling’s most complicated characters, is a friend or foe of boy wizard Harry Potter. The Unauthorized Harry Potter by Adam Troy Castro speculates about what’s to come in Rowling’s final installment.

Both titles were packaged for Borders by Dallas-based BenBella Books. They are part of Borders' larger promotional push, which includes the “Great Snape Debate” in-store advertising campaign. Deathly Hallows will be published July 21.
