Ig "Ignatius" Perrish, the son of a famous musician and brother of a famous talk show host was really going places. He has a job in London that he's moving for and a wonderful girlfriend named Merrin. Then one day, the police show up and arrest Ig. It turns out he's suspected of murdering Merrin, whose body was found showing signs of sexual assault. Months later, Ig is a drunk and overwhelmed by grief. Everyone thinks he killed Merrin, except for his brother. 
 Ig's downward spiral finally culminates in a night where he gets more drunk than usual and does some very sacrilegious things. The next morning he wakes up with what he thinks is a throbbing headache. When he looks in the mirror, he sees a pair of horns protruding from his head. Like any normal person, Ig decides to go see a doctor about his new look. On the way, he discovers that his horns make people confess their darkest desires and temptations. Finally, Ig decides to use his powers to find Merrin's killer...no matter the cost. Even if that cost is his soul. 
 I really loved the idea behind this book. I thought the idea behind the "confessions" was actually very clever and thought-provoking. If the people you knew had to be honest about what they thought of you, could you handle it? I kept putting myself in Ig's shoes and wondered how I'd handle hearing what my parents and significant other thought of me. 
 I really recommend this book to anyone that wants an interesting read. The book does have explicit language and very adult themes/situations. Some people may find problem in how religion is handled as well. This book could be really enjoyable for anyone able to keep an open mind.
