Dante Walker is a Collector. He collects the souls that Boss Man wants without question, slowly corrupting them until they've committed enough sinful acts to cover their soul in seals. When he's sent after Charlie, he has his eyes on promotion. Free to walk the earth and the Boss Man's right hand man? It doesn't seem like a bad deal, but Charlie isn't what Dante expects. Still it's her or him. If he doesn't collect her soul, he'll be condemned to the inner circle of hell and there's no way he'll let that happen. 
 The Collector is your straight up pure-good-girl-saves-the-bad-boy-from-his-bad-ways story, but told from the male perspective. Dante is an ass, but he's a lovable ass. His voice is intriguing and entraining (sometimes in ways that make me cringe as his jokes are at the expense of others). He undergoes quite a bit of growth in this book and I'm interested to see how his arc continues. Charlie is naive and sweet, but do not mess with her friends. She is fiercely loyal and also a big ball of sunshine despite traumatic events in her life. Overall, a highly enjoyable book.
