Flip by Martyn Bedford

One morning high schooler Alex Gray is shocked to find himself in a strange home across country with a new set of parents.  Even more shocking, the person he sees in the mirror is not himself.  Somehow Alex is now occupying the body of a handsome, athletic, popular teen named Philip Garamond--"Flip" for short.  Totally confused, Alex fakes his way in Flip's body until he can figure things out.  Although he is fascinated by the advantages of occupying a nonasthmatic, good-looking body--he yearns to have his old life and family back.   The plot is just a bit unbelievable at times, but I could not put the book down until I finished!   It's a very satisfying story--complete with humor, mystery, spiritual questions, and romance.
