   Summary

   Sunday has grown accustomed to the world being cruel to him and his little sister. So when they are rescued by a hitman who turns out to be more caring toward them than anyone else ever has been, Sunday has no intention of letting him go.

   Still, admitting to himself that he’s fallen in love with Gallagher is too hard. So, Sunday plans to ride him while he’s asleep.

   Somehow, this works.
