Cynthia “Sin” Breaker used to be a lot of things. A werewolf. A mob enforcer for a powerful mage. A name feared on every street of Solar City. But now she’s forcibly retired from all those things, trying to get over her past job and past loves. Zac Zero is a mage with their own agenda, and right now, item #1 is to hire some protection. Normally, Sin wouldn’t look twice, but Zero may have the key to getting back the most important thing she ever lost: herself.
