The Lost Prince by Julie Kagawa (Iron Fey Series)

Don't look at Them. Never let Them know you can see Them.
That is Ethan Chase's unbreakable rule. Until the fey he avoids at all costs—including his reputation—begin to disappear, and Ethan is attacked. Now he must change the rules to protect his family. To save a girl he never thought he'd dare to fall for.
Ethan thought he had protected himself from his older sister's world—the land of Faery. His previous time in the Iron Realm left him with nothing but fear and disgust for the world Meghan Chase has made her home, a land of myth and talking cats, of magic and seductive enemies. But when destiny comes for Ethan, there is no escape from a danger long, long forgotten.

Ethan Chase is back, the little boy who was the start of the Iron Fey Series by Julie Kagawa.  In The Lost Prince, he is all grown up and is now the hero of his own book.  If you haven't read the Iron Fey Series I do suggest you read those 4 books first before starting this one, since this pretty much takes up from where the series ended after a small time jump.  Because I like the Iron Fey Series I pretty much enjoyed this one.  There are similarities in the plot, boy sees the fey, boy gets in trouble a lot, boy meets an interesting girl with her own secrets and boy gets thrown into an adventure into the one place he detests.   The story stands very much on its own two feet however holding the reader in a new twist of Fae myths.  The Lost Prince also heralds the start of a new series, thinking spin off here, which introduces us to new characters and also revisits old, familiar ones as well.  Overall a very good read.  Good characterization, believable plot lines and wonderful writing style from the author Julie Kagawa.  Fans of the series will enjoy this while fans of the fantasy genre can give it a try and probably won't be disappointed.

Title: The Lost Prince
Author: Julie Kagawa
Publisher: Harper Teens
Genre: Urban Fantasy
Rating: ♨♨♨♨ (4 steaming cups of coffee.  Good plot, good characterization, however this is the start of a new series so if you are up to starting another urban fantasy long story line then it would be worth the time to read it.  The other plus, I do love the cover artwork not just for this book but for all the other books in the Iron Fey Series. I think for this one it did capture Ethan Chase the little boy grown up into a 17 year old young man)
