Being a dad, I'm not a typical reader of YA novels, but as a man with 3 teenage daughters, I like to know what they're mentally ingesting sorta speak. I think the storyline is clever, not your normal vampiry angst ridden characters. I don't know how prevalent these Paragons are in literature, but I enjoyed reading about their world. I think the characters are believable. It's not a bad concept, thinking that they're behind the scenes making sure that everyone has a soul mate. This stuff about what souls look like was rather inspiring, as I remember the awe that accompanied the birth of each of my daughters and the first moments I held them, how fragile they seemed. I think the writing is fast paced, I didn't get bored, which really surprised me considering the subject matter. As a parent I can enthusiastically recommend. It's rather refreshing. And since my girls are hooked on the series, I will be reading along too.
