Knight of the Demon Queen

The book i chose is called Knight of the Demon Queen by Barbara Hambly. I chose this book because to me this book was very eye caching.The book starts out like this...Once the most powerful wizard  in the land, Jenny Waynest is now a broken woman. After being possessed and corrupted by the demon Amayon, she lost everything she holds dear, even the trust of her husband, but Lord John Aversin has torments of his own, memories of the beautiful and cruel Aohila, demon queen of a rival hell, who he tricked into providing the help he needed to free Jenny. Now, condemned to death for trafficking with demons, John cannot forgive himself for opening the door to a far greater evil--an evil that still haunts his dreams. And not only his dreams . . . Two things liked about this book is that this book is so awesome, and just another action packed page one turn ahead. Two things i did not like about this book was that this book was 263 pages long, and that this book leaves you hanging at the end of the book :( .
I think the age group for this book would be 12+. i would recommend this book to any one who likes action.
