Micka and Me

My name is Mina Marley and I live in a town where supernatural beings live before they integrate into human society. My life is easy, but when I am told that I must house an angel called Micka it changes everything for me in heartbeat. Micka has a tattoo on his hand that matches a birthmark near my belly button. What does this mean?
Now someone is out to destroy my small town after they kidnap a little Faerie boy. These people want me dead all because if I live this Faerie boy will not live to be the great human he is destined to be.
Micka is my protection but why does mine and the boy's destiny entwine and why can't we exist together?
