The Directive (Mike Ford 2)

Never bet in another man's game, they say, but what if that man is your brother and the hand he's been dealt is lethal? Michael Ford has worked tirelessly to escape his criminal past and finally has it all: a beautiful fiancée and a promising career. Yet his brother Jack's return threatens to unravel everything. Embroiled in a billion-dollar conspiracy against the Federal Government, the only way Jack can come out alive is with Mike's help.
Sucked back into the dark criminal underworld against his will, Mike soon realises the only way to secure his future is to walk straight back into his past.
