Barr, Nevada. Borderline.
An Anna Pidgeon mystery, Borderline follows Anna and her new husband Paul on a delayed honeymoon intended to help Anna recover from some of the terrible events that occurred in the previous novel Winter Study. The novel opens as the couple, along with their guide and several college students, are rafting the Rio Grande in Texas's Big Bend National Park.
First, they encounter a cow stranded on a ledge and attempt a rescue. This incident reveals the dynamics of the group of rafters. Shortly thereafter, an accident causes the loss of the raft and most of their provisions. When they then discover a woman tangled in debris, things become much more desperate (I'm avoiding some spoilers here).
The mystery has several intertwining threads concerning Anna's recovery, the environment, politics, and issues involved in closing the border between Mexico and the U.S. after 9/11.
I have enjoyed most of the Nevada Barr mysteries I've read and this one kept me eagerly turning the pages.
