Flying Between the Realms. Altered Pilots, #1

Del wakes up severely hungover, drugged, and trapped in an isolated desert shack with no memory of how he got there. A mysterious voice delivers a chilling ultimatum: he has exactly twelve minutes to run one mile to a jetway, and any delay will result in his death. This isn't a kidnapping-it is the brutal, unannounced interview for a highly classified special projects initiative known as the "Singularity" program.
