They both include main characters hiding secrets from each other. The brothers in The Heart Killers are assassins for their "mom" while Kinn and his brothers are part of a mafia family that regularly kills people to get what they need. KinnPorsche has morally grey characters like VegasPete, which are similar to KantBison in The Heart Killers (in the beginning).
The themes and the tone of KinnPorsche are much darker than The Heart Killers but I do think if you like one you'll like the other.
