Iron to Iron — Ryan Graudin

Once upon a different time, there was a boy who raced through a kingdom of death.

Sixteen-year-old Luka Löwe has one goal in mind: Win the 1955 Axis Tour and become the first Double Cross victor. If he can accomplish that, maybe his father will finally see him as a worthy son. He's completed the grueling trek from Germania to Tokyo before, but this time is different. Luka never expected to meet Adele Wolfe, another racer posing as her twin brother and with a singular dream--to live life on her own terms.

When Luka and Adele form an alliance, an unlikely bond forms, and even possibly love. But only one person can win the Axis Tour....Can everything Luka and Adele built together survive the race?
