This was a great book. I gave this book 5 stars because I enjoyed it a ton...despite the lack of good editing. Commas are a weakness for Manning, it seems. ;)
However, it is easy to please me. All I need is a story (preferably first person) from the POV of a powerful magical being, and the more powerful he is compared to everyone else, the more I like the story (I suppose that there is a point where the main character's power would solve all problems quickly and ruin the book, but I've never read any so far). The main character in the Line of Illeniel (Mordecai...I think I spelled it right :P) has a fair amount of power, but nothing is too easy.
One point I especially enjoy in these Mageborn books is Mordecai's willingness to research. There are so many (I repeat, so many) books where the main character discovers he has magical powers. And then...does nothing much. This character only learns more about his/her power when using it in a tight situation or something. But Mordecai actually experiments and is willing to research. +1
There was some more depth to this book than the first one, in my opinion. It was able to get me slightly emotional, which is a big achievement since I don't usually get emotionally influenced by books (although I am susceptible to humor...).
