Two books in one box. Willow Rose's I Am Wolf and Song for a Gypsy. Both are part of the Wolfboy Chronicles, the story of the life of Sami the Wolfboy. 

Originally he was just one of the characters in Song for a Gypsy but later his story was told in I Am Wolf.

I Am Wolf: They call me Wolfboy. Of that very simple reason that I am part-wolf, part-boy. I'm not immortal as many people might think, but I will live longer than most. Thousands of years longer. I am immune to all diseases, I am stronger than most other beings on this planet, and I have lived through many wars and sustained much pain in my life that no human could ever do. I heal easily, but I do get hurt. I have. Up until this day, I've never told anyone how I became who or what I am. This is my story. 

I Am Wolf is a paranormal thriller with some violence and sexual situations recommended for ages 16 and up. 

Song for a Gypsy: Sara's life is drastically changed the moment a convoy of horse-drawn caravans enters the quiet Reidenburgerstrasse, where she lives with the people she thinks are her parents. Sara doesn't know that her parents found her in a basket on their doorstep 13 years earlier. Neither does she know that she is a gypsy or that she is going to be the greatest sorceress who has ever lived. Soon, Sara will discover a magical world she never knew existed and go on a journey that she knows will cost her dearly. 

In Song for a Gypsy, we meet Sami the Wolfboy for the first time.
