The first series I read by Jennifer Lynn Barnes was Raised by Wolves. In that series, she impressed me with her strong, young heroine and unique take on a old tale about were packs. In that story the heroine is a human who has been raised among a pack of werewolves. In Every Other Day, she continues her trend of strong, young heroines who do the best they can to deal with their fate. In this story, that girl is Kali D'Angelo, a teenager who every other day is a somewhat typical teenager who has problems relating to her dad and avoids forming friendships. She avoids friendships because every other day she is a demon hunter. On those days, she is no longer a weak, meek, human girl, but something other, something stronger, without pain or fear. In her world, the paranormal is normal. Creatures such as hellhounds and zombies are not a myth, but reality. She kills them to protect others. She's been doing so since she was 12 years old, but doesn't know exactly what she is. That is only one of the questions she hopes to answer.When Kali's father decides that the "small environment" of the gifted program at his university wasn't good for her "developing social skills" and sends her to public school, she is none too happy. But, as she is zoning out during a pep rally, something unexpected happens ... she makes a friend. Skylar Hayden, labeled as the school slut, befriends Kali. And, her quirkiness and habit of rambling instantly endeared her to me and Kali. One of Skylar's many brothers is dating cheerleader, Bethany Davis. Bethany is the daughter of Paul, who is the new head of Kali's father's department at the university. These three, Kali, Skylar, and Bethany, form an odd friendship that grows into much more when together they fight the things that go bump in the night. These two friends help Kali when she is used to tackling things on her own. Each of the girls is strong, yet very different. It was fun watching them interact together, especially in some intense situations.The story is full of fast-paced action, wild creatures, conspiracies and mysteries. There are instances when I felt the author could have explained a bit more, but I know she enjoys having the readers guess and figure things out along with the characters in her story. Though I didn't feel an instant connection between Kali and her would-be beau, Zev, I was intrigued by him. The ending of this book left a lot of questions. It felt a bit rushed, but I'm hoping the existence of those questions means there will more books, making this a series, so that we can discover how things progress. (Full Rating: 3.5★)
