Junkyard Riders by Faith Hunter

Shining Smith returns, taking on the “Dark Riders,” a paramilitary group motorcycle gang searching for Gov. political power, military connections, and alien tech. The Dark Riders are closing in on Shining’s secrets and, while she would rather nest in her new roadhouse, Shining must protect her own, once again taking the battle to the enemy.
Unfortunately, CAIT, the original AI on the junkyard’s crashed spaceship, has its own agenda buried in the ship’s code and choses this time to implement it. There is nothing Shining can do to stop it, except what she does best – plot an offensive, get her people in place, and hope Jolene can outsmart the virtual alter ego.
But the cataclysmic snowstorm crashing in with all the power and subtlety of Mateo in his WarBot suit could be the end of them all.

Book 5 in the JUNKYARD CATS series.
