Olena Wilder is just your average teenage girl, who does normal teenage things. She knows how to kill a person at least fifty ways in hand to hand combat, she's trained in the lethal use of weapons, she knows multiple types of martial arts, and she's very good at killing people, say rogue vampires who set out to destroy their much more society-accepted counterparts, or her distant cousins from Russia who are set out to regain their pact with the Devil and destory her family.
