Die Trying by Lee Child

Jack Reacher, alone, strolling nowhere.

A Chicago street in bright sunshine. A young woman, struggling on crutches. Reacher offers her a steadying arm.

And turns to see a handgun aimed at his stomach.

Chained in a dark van racing across America, Reacher doesn't know why they've been kidnapped. The woman claims to be FBI. She's certainly tough enough. But at their remote destination, will raw courage be enough to overcome the hopeless odds?

Although the Jack Reacher novels can be read in any order, this is the 2nd in the series.
