YA is the publishing term for novels aimed at Young Adults -- though in actuality, the age range of the readers is fairly elastic -- from preteen to early twenties -- or, in my case, late sixties. The protagonists, however, are almost always in their late teens and the story is often that of a coming of age.
Recently I've been wandering in this genre. Jo Walton's Among Others is a quietly charming novel about Mori, a young girl who has run away from her mother in Wales to England and the father she hardly knows. Set apart from others at her boarding school because of a crippled leg, she spends much time reading -- and a great part of my enjoyment of this books was that she reads many of my childhood favorites.
Oh, and Mori's mother is a witch - an evil one -- and Mori herself can do magic and . . . well, there's a detailed review HERE. I really loved this book
Another YA that I recently enjoyed is Lev Grossman's The Magicians. It's a kind of American and more grown up Harry Potter and there is, I might warn you, Language, as well as Adult Situations. (Not surprising for this late teen, early twenties age group.) I also caught quite a few nods to Narnia. This is another fantasy meets real life. I was completely engaged by the characters and would like to read a sequel.
Not a YA, Live Wire is the tenth in Coben's NYT bestselling Myron Bolitar series. I've written here before of my total fascination with this wise-cracking, sweetheart of a protagonist as well as his psychotic preppy ninja sidekick, Win. (In this outing Win has two Asian girlfriends, named Mee and Yu, affording the opportunity for a lot of punning.)
And there's another new character -- Myron's nephew Mickey. He's a wonderful, conflicted teen with serious family issues. All of which makes him perfect to be the protag of his own YA novel.
Shelter, with Mickey in the starring role, is just out. I haven't read it yet but I will, I will!
