The Perfect Plan by Bryan Reardon

A twisty tale of two brothers, bound by blood and divided by hate. Liam is the younger, the screw-up, the out of control violent one as opposed to Drew who is calm, friendly and knows how to manage a situation. A tough childhood with an alcoholic mother and domineering father leaves both brothers changed and relying on each other. Drew is running for Governor and one of them has a plan for boosting his appeal. You think you like one and not the other, you think one is out of control and the other always in control and you think you know how the plan is going to work - you know nothing. Gut-wrenching psychological manipulation and an ending you won't see coming, this is a solid thriller.
