This book is chock full of history, mythology and plot. Add to that it's written from the point of view of the Seer and not necessarily one of the main characters the book focuses on (Keleigh/Locke), you have the potential to be overwhelmed. I think I can safely say this book is not meant to be read quickly or skimmed through - it's intended for those that can sit down and fully immerse themselves in the rich details written on page upon page. If you have that sort of time, then you definitely won't regret it.
There was an amazing cast of characters starring in this book. Keleigh is the sort of girl that just tries to blend in with everyone else, when she truly stands out no matter what she does. Locke is a wild spirit that I honestly can't pin down with just a few words because he is truly everywhere with his personality and emotions. Both Keleigh and Locke's best friends are amazing supporting characters, full of charm and loyalty. Over all of the characters though, I think the Seer was the one that struck me as one of the most intriguing. Perhaps it was because the book was from her POV mostly, but her personality and wit really added another level to the story. It was strange to read the story from a secondary character's perspective, but it also added something unique to the story that I don't think would have been present had the POV from the story been from someone else. And even though the story is told from her POV, the Seer is still something of a mystery that keeps the element of intrigue that isn't necessarily quenched by the end of the story - making it impossible not to want to read more about her.
All's Fair In Vanities War has everything that I could ask for in a great read and I cannot wait to read more. If after reading my review, you're not in the least timid by this book... then I would wholly recommend checking it out.
