Vengeance Road by Erin Bowman

Revenge is worth its weight in gold.

When her father is murdered for a journal revealing the location of a hidden gold mine, eighteen-year-old Kate Thompson disguises herself as a boy and takes to the gritty plains looking for answers—and justice. What she finds are untrustworthy strangers, endless dust and heat, and a surprising band of allies, among them a young Apache girl and a pair of stubborn brothers who refuse to quit riding in her shadow. But as Kate gets closer to the secrets about her family, a startling truth becomes clear: some men will stop at nothing to get their hands on gold, and Kate’s quest for revenge may prove fatal.
