Want a DARK novel to read for Valentine's Day?

Joe Hill, Stephen King's son, wrote a book that was published a few years back about a guy named Judas Coyne. Judas is a mature rocker that is a collector of macabre items. When he gets an email to add one more dark item to his ever-growing collection he can't resist the temptation.  Heart-Shaped Box speeds through to the climax.  Rock, goth, fear and death for the masses, good job Joe.
