Bone to Pick (Digging Up Bones #1)
T.A. Moore

This time the missing person is a ten-year-old boy who walked into the desert in the middle of the night and didn’t come back. With the antagonistic help of distractingly handsome FBI agent Javi Merlo, it quickly becomes clear that Drew Hartley didn’t run away. He was taken, and the evidence implies he’s not the kidnapper’s first victim. As the search intensifies, old grudges and tragedies are pulled into the light of day. But with each clue they uncover, it looks less and less likely that Drew will be found alive.
