Blood on Blood - Ania Trilogy, #1

When half-brothers Mick and Jerzy Sawyer are summoned to their father's prison deathbed, it isn't for a tearful goodbye. The spiteful old man tells the two estranged brothers about an old diamond heist with outstanding loot, and sets them on a path of cooperation and competition to recover the jewels. Jerzy is the quintessential career criminal, fresh out of a short bit and looking to get back into the action right away.
Mick is the failed cop and tainted hero struggling to get by with a clean life that doesn't seem to ever pay off. Both men see this score as their ticket out of Chicago. Throw in the mysterious, blond Ania, and Blood on Blood is hardboiled Hardy Boys meets Cain and Abel. Jerzy and Mick battle each other for all of it - the diamonds, the girl, and survival - and nothing else matters.not even blood.
