The Vulture King

Orphaned Aram has survived alone for five years, his only friend a thieving magpie, who acts as his eyes. For in the Carrionlands, magic comes at a terrible price. It costs you your sight, hearing or voice.

When he rescues a voiceless girl, Bina, from being sacrificed to the Vulture King, he is taken in by an underground resistance group. They reveal that Aram's mother is alive, but the king is using her and other slave magicians to fuel his unnaturally long life.

With his mother's magic being rapidly drained, she doesn't have long to live. If Aram can find the Radix, a hidden magical power source, there's a slim chance he might be able to save her. But to get there, he must cross the Barrens where every living creature is out to kill you. That's if one of his new companions doesn't betray him first.
