A Wolf to Watch Over Me — Sela Carsen

In a future Earth, sometimes the Big Bad Wolf is the good guy. Hakon sidUlfr , a wolf shifter from another world, is better at killing than guarding, but quiet physicist Lauren Ivers will need all of his skills if they're going to live through the day. Lauren should be at home, reading and eating take-out. Instead, she's on the run with the bodyguard she didn't know she had in a desperate bid to get off the planet before she becomes a casualty in an intergalactic cold war. Hakon's deep instinct to protect the smart-mouthed scientist keeps her alive, but will she stay with him once his duty is done?
