Magicians Impossible — Robert Bradley Abraham

Jason Bishop's world is shattered when his estranged father commits suicide, but the greater shock comes when he learns his father was a secret agent in the employ of the Invisible Hand, a brotherhood of spies wielding magic in a covert war. Now the Golden Dawn, the ones responsible for Daniel Bishop's death and the death of Jason's mother years before, have Jason in their sights, and his survival depends on mastering his own dormant magic abilities.

But enduring the Invisible Hand's rigorous training may not be enough to turn the tide. Jason's first mission ends in disaster and he's captured by the enemy. Taken to its leader―the enigmatic Red Queen―he's ready for anything, except the revelation that the Invisible Hand is the real threat, committed to using mastery of magic to subjugate the world with only the Golden Dawn in opposition. Jason has been fighting for the bad guys all along, and he's the one who can tip the balance of a war that has raged since creation.

But in a world cloaked in mystery and magic, who can Jason trust? The Golden Dawn, who claim to hold the secrets behind Jason's mysterious lineage? The Invisible Hand, who've been more of a family than his own family ever was? One thing's for certain: the magic Jason Bishop has been mastering is telling him not to trust anyone.
