Atlas: the Story of Pa Salt (The Seven Sisters # 8) (2023)

A boy is found, moments from death, and taken in by a kindly family. Gentle, precocious, talented, he flourishes in his new home, and the family show him a life he hadn't dreamed possible. But he refuses to speak a word about who is really is.

As he grows into a young man, falling in love and taking classes at the prestigious Conservatoire de Paris, he can almost forget the terrors of his past, or the promise he has vowed to keep. But across Europe an evil is rising, and no-one's safety is certain. In his heart, he knows the time will come where he must flee once more.
