The magic thief. Book 1 - Sarah Prineas

Conn should have dropped dead the day he stole a wizard's locus stone, but miraculously he survives.
Becoming the wizard's apprentice, Conn becomes embroiled in his master's plan to save the city, whose magic is slowly dying. Meanwhile, the Wizard, Nevery, is secretly beginning to question Conn's past: Why did the thief survive in the Twilight and why is he immune to injury? But Conn is hiding a much darker secret . . .
Sarah Prineas has imagined a richly detailed magical world like no other.
