I was absolutely hooked on this book from the first page. I read it in one sitting because I couldn’t put it down! ERR394N was created by a crazy scientist who was put to death for his foolishness. However, she already existed and has been known since as the hybrid mistake. A fearless assassin given the worst assignments, probably hoping that she would fail and never return to the Icarus Realm, which is where the League of Supernatural Assassins is. But she has a plan to escape. She just needs to complete this one last assignment and then she will put her plan into play. She is sent to Earth to kill one Davian Harbor. Something doesn’t seem right with the information she was given. But when she meets him she realizes he is her mate. Assassins aren’t supposed to have mates. When Davian finds ERR394N in his backyard with his little sister Martina, he is pointing a shotgun at her. But Martina has decided that she is her friend and they are going to help her fix her broken leg. When Martina finds out she doesn’t have a name, she names her Erryn. And just like that she becomes a part of their patched together family. But if Erryn wants to stay she will have to figure out a way to get the League of Assassins off their tail. A great book with lots of emotion and action. You will fall in love the Erryn and Davian and the three girls just like I did. Great start to a new series. Can’t wait for the next book!.
