Past Due - Savannah Martin Mysteries , #8

The sins of the past are coming due, and someone has to pay... Savannah Martin's high school reunion is supposed to be a fun weekend of catching up with old friends and parading her boyfriend-Sweetwater bad boy Rafael Collier-in front of everyone who used to sneer at him back in the day. Not even the daily battle she's waging with morning sickness can douse Savannah's anticipation. But when Rafe won't come to Sweetwater, Savannah has to face her old schoolmates without his support.
And her best friend Charlotte isn't as happy for Savannah's new relationship as Savannah had hoped. And when a dead body turns up in the Colliers' old mobile home in the Bog, Savannah is thankful to be on her own. The sheriff is always looking for a reason to shove Rafe back behind bars, and a fresh homicide is just the excuse he needs. But when another murder takes place at the reunion, even the threat of jail can't keep Rafe away.
Soon old classmates are dropping like bowling pins, and Rafe and Savannah are scrambling to catch up with a killer hell bent on making sure old enemies pay for old sins... all while trying to stay one step ahead of Sheriff Satterfield and the Columbia PD.
