You are my full moon

Kian is a mystical beast, able to turn to human form. He got captured by a warlock and is now merely an object in his possession, a weapon. Kian doesn't remember much about his past and gets further and further detached from the world until he meets Liérinn, a halfbreed boy. He is half elf half human and doesn't fit in anywhere. They meet in the most remarkable way and Kian's stone heart somehow opens up to this little boy. Can their bond save them both?
