This month’s Mystery title

Borderline
by Nevada Barr
Hoping the adventure of a raft trip in Big Bend National Park will lift her spirits, Paul takes Anna to southwest Texas. Instead of the soul-soothing experience they’d longed for, the couple finds a pregnant woman–more dead than alive–and soon they are sucked into a labyrinth of intrigue that leads from the Mexican desert to the steps of the Governor’s Mansion in Austin.
