The Fall Moon — Blake Banner

When Karl and Christen Redfern were brutally murdered in their apartment in the Bronx, a lot of things were never explained, like why he was stabbed only twice, with clinical precision, but she was stabbed twenty times in the heart, in a crazed frenzy; like what happened to their Chevy Impala, and why Christen's sister, Ingrid, had never reported it missing. But the biggest mystery of all was perhaps where Karl and Christen's daughter Amy had disappeared to, along with her boyfriend, Charlie, on the very night of her parents' murder.

These were the questions Detective Carmen Dehan of the 43rd Precinct had been asking herself for the past six years. But when she persuaded her partner, Detective John Stone, to take this as their next cold case, he was anything but prepared for the passion with which she would then pursue that investigation â€" an investigation that would take them from the Bronx to Iowa, and then Arizona and the Mexican border, an investigation with layers of dark secrets that would ultimately bring them face to face with Sinaloa's most ruthless Sicario, and test their relationship to the very limit.
