Old wounds can leave the deepest scars. Lance Corporal Ren Inouye has spent a decade forgetting his homeworld and the girl who cut out his school-age heart. With the help of his umbra wolf partner, he's almost succeeded. When he's ordered back home, the last thing he wants is for her to drop back into his life and tear open those scars he thought long-healed. Lucia has spent five years doing refugee work, trying to make up for her family's name and her own spoiled childhood. When her aid shuttle gets shot down, she's forced to rely on the one person she thought she'd never see again. Thrown together, it's impossible to ignore that their old passions still run hot. If they want a future, they'll need to put the past on hold and work together, because someone's trying to heat up a cold war on their homeworld, and the fastest way to do that is to make sure they're both dead.
