Crimes Against Magic

Nate Garrett woke up in a warehouse with no real memory of who or what he was. For 10 years he has been working as a thief with magical powers.
As his past comes back to haunt him, he has to look after the people he's grown close too as they become pawns in a game that has been thousands of years in the planning.
Good characters and a mix of old and new magic make this a good start to a series.
