A vacation out of the city sounds like just the ticket for Tori Hunter and Sam Kennedy. Joining their Dallas Police Department pals Casey O'Connor and Leslie Tucker in a rented RV, they set out for the New Mexico mountains - and on a collision course with a manhunt. FBI agents Cameron Ross and Andrea Sullivan are tracking a deadly quarry in desolate territory. An ex-teammate from Cameron's Special-Ops days is in deep hiding, planning who-knows-what to cap off a killing spree.

With a hostage at stake and time running out, Cameron reluctantly agrees to outside help from women she doesn't know...or trust. In the crossover that fans have been clamoring for, it's a heart-pounding race against time that challenges the courage and commitment of the exceptional women from Gerri Hill's Hunter's Way and Devil's Rock Series.
