A Necessary Sin (The Sin Trilogy, #1)

Bleu MacAllister is consumed. A horrific childhood incident has caused every decision in her life to revolve around bringing a monster to justice. With years spent studying The Fellowship, an organized crime brotherhood of liars, thieves, and killers, Bleu will rely on her skills as a special agent to cut Thane Breckenridge off at the knees. But walking hand in hand with retribution means risking collateral damage, in the form of Breckenridge’s son Sinclair—until Sin becomes so much more than Bleu bargained for. She’s always known this undertaking would place her life in danger—she never imagined her heart would be as well.
